gamemaker studio 2 tutorial drag and drop
Dodane 10 maja 2023The page you start on is the to make our player move around the screen. section on it, which will open the Room Editorin its own workspace: Rooms can be used for just about anything. While this isnt a full game, its enough to get a good feel for how GameMaker Studio works, and whether it clicks for you. spr_damage You don't even have to worry about placing it properly because we've taken care of that in the Create Event of the object. This is necessary because the tiles themselves are in the Tile layer and dont have any impact on our game objects. (for the sprite). I'm no programmer at all, so I would need to use the drag & drop mode. By default this is set to 30 by GameMaker Studio 2for any new project, which is fine for puzzle games, or games that don't require fast response times or even for mobile games, but for arcade style games like ours a preferred value would be 60. No matter how you set things up, if you don't enable views then nothing will change, so this is very important! x At the moment it's 32px, which means that the player would have to move right up to the edge of the view camera window before it will move to follow, which in an arena shooter like ours is just too small we want it to move before that so that the player can see what is around them. Now your player object is in your room, and therefore part of the game. Getting Started We will be using an After you change it you will see that the room in the editor has now expanded to twice its width (you can use the zoom controls to expand the viewable area if you can't see the changes, or alternatively hold down / and then use the mouse wheel to zoom in/out). So, objects are in the resource tree, and are then used to create the instances that populate our game room. section. The "type" should be set as the direction, as we want to use that rather than the horizontal or vertical component. / + to open the workspace switcher and select the editor that you want to see directly. For more developer tutorials and news from Android Authority, sign up below! obj_damage top left You can delete it, and you can edit it, and you can create further rooms using the right button Well, so far we haven't added anyDraw Event to anyof our instances, and yet they all draw their sprites to the screen when we run the project. So, open this object now for editing and go to the Step event and add this action just before the Destroy Objectaction : With that added all you need to do is select the sound to be played from the menu (there will only be the one sound that we have added), and there is no need to check the "Loop" checkbox, as that will make the sound loop continuously until the game ends or we call an action to stop it. This is because when you don'tadd a general Draw Event to an object yourself, GameMaker Studio 2will automatically assume you want to draw the sprite assigned to the instance along with any transforms (like colour or alpha or scale) that you have added. Now let's add some code to the player object. Objects We've seen built-in variables already, but this is one you are creating and it's called an instance variable. section But you can change it to We are going to make a new object and call it So, if you hold down A for one second time will increase by 0.6. Clicking this will animate the whole room such that any backgrounds that are set to move, or tile sets that are set to animate, or any sprite assets that have sub-images will be shown as they would appear in the game: With the horizontal background speed now set to -2, this will add interest to our title screen, we can continue on to make our title object. As you may expect, the collision event runs its code when the two objects collideor, more precisely, when their bounding boxes touch each other. this video has not coding. at the top left of the IDE. The Sprite Editor will now look like this: The top part of the editor will show a single image, and the main window will have a larger preview. Many careers in tech pay over $100,000 per year. It has everything you need to take your i. To get our score to go up as we play, we need to add some extra actions into the Step Eventof the object obj_enemy, so open that now if it is not open already. . However that won't work in this case, as there are multiple enemy instances within the room and GameMaker Studio 2doesn't know which one you actually want to affect. While you've been testing your game, you may have noticed that the bullets don't often actually appear to hit the enemies when they disappear yet the hit is being registered, and the bullet is disappearing and the enemy "hp" is being affected. With the Room Editor workspace open, you will see that most of the screen is taken up with a large black area with grid squares over it. ) and move the instance with the arrow keys: We are almost finished this tutorial, but there is one final thing we want to happen with our player instance We need to make it rotate to always face the mouse while it is being moved around the screen. sections. So I WOULD have a problem with graphics, right? You can get quite far using the drag and drop system, but really it depends on what you want to do and how complex you want to design your project. We will do this a little later on in the tutorial, so don't worry about it just now and we'll just use the "Instances" layer to start with. Large triple-A studios start with a long design, concept, and prototyping process. Once the level has been drawn, we need a character to explore it. Objects Create a new In this case we are going to add an action to the event to make the player instance move right across the screen. To open it for editing you need to double-click Things to consider adding to this project would be: The list could go on and on, but it's entirely up to you what you do from now on. You can close this sprite now and we'll move on to creating the title screen room. In this event, we will add the following Assign Variableaction : "hp" is an instance variablethat we want all instances of this object to have, and it will store the "health points" for the enemy object. This will take us back to our main workspace and focus it on the object we want to edit. In this tutorial we will simply be adding a single sound effect when you destroy the enemy instances, so you can use any sound effect that you have on your hard-drive or you can use the one that we have supplied along with the tutorial, which will be found when you open the file explorer in the TutorialResourcesfolder, in the "Sound" sub-folder (if you have any issues, you can also find the sound here). We actually need to use a functionto get the angle that we want to set the sprite to, and then we'll store the value it returns in a variable ready to set the rotation of the instance. With them all selected simply press the key to delete them. Play your game again now and note how the sound changes every time you destroy an enemy. , then click That's not very satisfactory for the player! , or Before continuing to add these spawner objects, we first of all need to remove the enemies that are currently in the room and prepare a new instance layer, so open the room "rm_game" now. What this does is to automatically divide the image into blocks of 3232. and then add it to the player object. Now for the fun part of this GameMaker Studio tutorial: building a level or room. Rooms are screens that can represent levels of a game or chunks of a level. which will be a completely empty object with physics once again disabled. So, still in the obj_enemyStep Event, and before the action for playing the sound, we need to add the action Set Audio Pitch: When you use a sound effect or music in GameMaker Studio 2it is played with a pitch value of 1. However our tile set has all the tiles packed right beside each other, so we don't need to worry about this. This is a simple way to animate your character while moving. event and a new window containing a text editor to type your code into. we are going to dedicate to adding some sound to our game. This is useful for many, many things, not least of which is storing one-off values from calculations and saving memory resources. For now, lets put the section . In the step event, add the following code: The first thing youll notice is that the red box is moving much faster than your character. Next , select GameMaker Language instead of Drag and Drop . engine made for 2D games This is done from the background Layer Propertieswindow: The background layer is a layer that can be cleared to a single colour and/or have a single image applied to it. This will make sense in a moment! were to equal zero, our object would be at the far left of the screen, and if Now you should be able to slow time by pressing A and speed it up by pressing D. Congrats! we are going to look at an important aspect of any game keeping score. of this tutorial You've made it to the Scoring Section of the "My First Game" tutorial and in this event By the end, youll have built your first 2D platform game! Click on the Rooms folder in your Asset Browser, and youll see that you already have an asset called Room 1 in here. event will run only once, right when the object is created. we now have a nicer introduction to the game. Before you try it out, dont forget to drag your world object into the room with your box and player. x If you select it then you'll see the event added into the Event Editor window and a new window chained to it: The new window is the DnD Editorand is split into three parts: The idea of Drag and Drop is simple - you select an action from the toolbox and drag then drop it onto the action workspace. Its really important to type everything exactly when youre writing code. Lets make sure it all worked and press Later, we can come back and draw some animated sprites that resemble more than a box. Next choose the "Drag and Drop" option, which we will be using for this GameMaker Studio . Like Unity and Unreal, GameMaker Studio, is a game engine that incorporates a powerful IDE (integrated development environment) for easy development. By continuing you agree to our Terms of Service and Privacy Policy, and you consent to receive offers and opportunities from Career Karma by telephone, text message, and email. section , and add a new step event. You can name this sprite now, something like "spr_background", and close the sprite editor before continuing (we don't need to set the origin of this sprite nor any of the collision properties as they are not relevant for tiles). on resource name and call the room "rm_game". The most game need drag and drop object to customize.In this tutorial I will show you how to code drag and drop simply way.tags:gamemaker studio 2 drag and d. A sprite is an image that is combined with certain properties which is then used in the game to represent something. With this action, we check to see if there is an instance of the player object in the game room because later we want to access certain variables from that instance. Note that if you have several instances on the samelayer, then these will be drawn in the manner that is most efficient, normally from the first created on that layer to the last but this is not guaranteed. You should be familiar with how to do this so go ahead and make one now and call it "obj_score": The object "obj_score" will be our controllerobject and so we don't assign a sprite to it since we want it to draw other things (like the score text). Go ahead and run your game again. You should now have a player ship that can move and shoot, and bullets that are timed to come out at regular intervals. Resource Panel However, if you have zero coding experience, you should still be able to follow along. Debugging is no fun, so try to copy the code exactly. Youll notice you have some more options now. So, double click on the Player in the Asset Browser and then choose Events > Add Event. and rapid development: By doing this we are adding -1 relative to the current value, ie: subtracting 1 from the current value. section, we are going to show you how to set up a basic title screen for your game using a new room and with some extra graphics. section of the If you make your own sound effect, you should export it as a *.wav, an *.ogg or as an *mp3 format sound. F5 We are going to expand on the current actions to include a check to see if the "hp" variable we initialised previously is less than or equal to 0, and if it is we are going to destroy the instance (remove it from the game room). GameMaker Studio 2bases all the scale on factors, where a factor of 1 is 1:1 with the original sprite image, so a factor of 1.5 is 150% bigger and a factor of 0.5 would be 50% smaller. Were going to use the one we just made. F5 There are different types of workspace too, but we'll cover that a bit more later. We need to add a Collision Eventhere to detect the collision between the bullet (the calling instance) and "obj_enemy" (the colliding instance): Now, in this event we will need to affect the "hp" variable of the colliding instance, and we saw that we could do this using the "point" method previously. ). and section GameMaker Language vs Drag and Drop GML, or GameMaker Language, is GameMaker's proprietary programming language. Finally, how powerful is this software? Its a flat purchase price, meaning that GMS 2 doesnt try to take your games profits or make you pay monthly. section You can change this manually by clicking on the preview. obj_damage For that we'll use the following image in this tutorial, but you can create your own if you want: You need to click on the button This means that we now have to re-order the rooms so that the title room is placed before the game room. Every game needs sprites, so take yours and drop them into the Sprites folder. If it is, it sets the Y to zero, which is the top of the screen. , and you consent to receive offers and opportunities from Career Karma by telephone, text message, and email. This is done using the following actions, which you should add in after the current ones: The next thing to do is to make the "hp" variable actually go down, as currently that check will always return false since we only set the "hp" to 5 and nothing else. section This means that changing an instance's properties will not change the properties of the object it was made from, however changing an object will change all subsequent instances created from it. To start with open up the object "obj_player" and add a new collision event with the object "obj_enemy": In this event we need to add the following action to Restart The Game(from the Gameaction library): All this code does is (as you might imagine) restart the game the moment an enemy instance "touches" the player instance, meaning that we now have to not just shoot the enemies, but dodge them too. The origin cursor will disappear and a grey box will show up on your sprite. So double click on the object "obj_player" from the resource tree to open it in the current workspace if it's not open already. Instances are copies of the initial object placed within the game room. The origin is simply a point on the sprite that will be used to position it within our game room, and you can set it by either clicking In this case we use view port[0] since that is the one we set up in the room editor in the last section. Note that in the Font Editor you have a preview window that by default shows "Hello World". Now, create a new object (Ive named mine You can actually delete this and type in any text to get a preview of how it will look in the game. If both of those are true, then we increase time by 0.05.

If you need to change this, you can select the Collision Mask drop-down menu on the left, and then select Manual under mode. At the time of writing the engine is in version 2.3.1.542. Instance variables are valid for any event in an instance and can be changed or read in other action blocks. I know thats a very small number, but remember that this will happen 60 times a second. As with the sprite, we talked about how to create objects in the previous tutorial, so we'll only quickly run down how to do it here: Our new object will have the Eventswindow chained to it and ready for us to add some code into, but firstwe are going to go back to out player object and edit that a bit. Next Putting We want to now make the player instance move when the user presses the Arrow Keyson the keyboard. There are a lot of options here, but the first thing we need to do is switch the view "on". Rooms When you execute the module, you get the following output. If you want to know more about the different events in the Draw Event category, you can press to open the manual and read up on them in the section on the Object Editor. When ready, click the Play button to test your game and you should see that the enemies now scale into existence. Note that the assign variable action is placed to the right to indicate that it is only being run if the conditional check is true, and that this is also reflected in the action list on the left, where the assign variable entry has been tabbed too. We will use the same approach to scaling that we used previously for the image_alpha, so add the Set Instance Scaleaction and then we'll do an If Variablecheck on it: This will scale up the image xscale and image yscale by 0.02 every game frame (note that the relativecheck-box is marked) and then it will check the value of the image_xscale variable to see if it is greater than 1 and if it is it sets the scale to 1. First you would open GameMaker Studio 2, and then click on the New Projectbutton shown on the main Start Page: You will then be presented with two options: Drag and Dropis the powerful visual scripting language that permits you to code a project using chained action blocks, while the GameMaker Language (GML) is the propriety scripting language that permits you to create games using the code editor. All this will do is stretch the background image used to fill the whole room area, which with a small image like the one we are using doesn't look right, which is why we tile it instead. Note that even if the image you supply has non-transparent pixels in this first grid cell, they will not be drawn, so when making tile sets keep this in mind and just leave this first tile blank.
