The next step in our GameMaker Studio 2 tutorial is where things start getting really fun. setting is pretty smart, and it does a good job, so I wont change it for my sprite. There is a minor problem that we have to fix now, though GameMaker Studio 2will run rooms in consecutive order, meaning the room at the start of the room resource list is the one that will be shown initially when we start the game. Step 1. The second part of the code checks to see if the Y position of the object is at the bottom of the screen. Make sure to tick relative so that these positions are relative to the player object. A temporary or local variable is simply defined as one that is "local" to the script or event that is using it. We can expand the current action list now to cover the remaining three directions of up, left and down. The action can be found in the Mouse and Keyboardsection of the action toolbox and you should drag it into the action workspace abovethe Assign Variable action: Note that when you drag it near the existing action an area will be highlighted indicating that it can be placed either above or below the action in the chain (in the image above we place it above), and once you drop it you will see that it is connected to the Assign Variable action like this: That square chain on the left means that the "if" action will be called and thenthe Assign Variable action, but that they are independent of each other.

Go ahead and run your game again. But you can change it to Powerful. It is expected that you know some coding basics (like what a variable is), as this tutorial wont go too in-depth into how the code works. GameMaker Language vs Drag and Drop GML, or GameMaker Language, is GameMaker's proprietary programming language. This document is divided into three parts with the aim of getting you introduced to the interface and basic workings of GameMaker and general programming, before going on to more advanced usage and the functions available through our proprietary programming language GML (GameMaker Language).. To ease you into things we have created a handy Quick Start . If you run the game now, you'll get the title screen and pressing Enter will take you to the main game room to play. Getting Started Note that if we hadn't flagged the "relative" check-box, then we would be settingx to 4 rather than adding to it, and if we'd used -4 instead of 4, then we would have been subtracting4 from x. Care must be taken when using this action, though, as if there is noroom after the current one (ie: the room using this code is the last one in the Resource Tree) we will get an error which will cause the game to close. We could, for example, have created a "BulletsLayer" in the room editor, and then used that to explicitly say we want the bullets on a unique layer - the action for that would have been simply: You can see there that if a layer has been created in the room editor, we can use its name as an identifier to target it within this action (and a few others). The were to equal zero, our object would be at the far left of the screen, and if Go to The GameMaker name has been around for a bit, and many amazing and successful games have been made using this game development tool. By default GameMaker Studio 2will use a draw colour of white for everything, but at various points in your game you may wish to change this, and it's good practice to explicitly set the draw colour before drawing anything, so that is what we are going to do now as well as draw the text itself. Next we add in the Assign Variableaction just as shown above, only we chain it to the right of the Assign toaction, as we did for an "if": Finally we want to destroy the bullet instance by dropping an Instance Destroyaction after (and outside of) the Applies toaction, so the final Collision Event looks like this: After we take the point of off the "hp" variable, we then call the action to destroy the calling instance (the bullet). When you play the game you should here the sound being played every time the enemy is destroyed, however the sound will quickly become tiring to the ear of those that play the game. Now, you may notice that they dont do anything. To open it for editing you need to double-click Not assigning a sprite to an object means that when we run our game with an instance of that object in a room it will not be drawn, but that doesn't mean that it isn't doing anything. You should run the game again now, and you'll see that the experience is quite different to what it was before. In the next However sometimes you want to preview a change like this without having to compile the whole project to see how it looks, which is where the Animatefeature of the room editor comes in very handy. Events spr_player By default this is set to 0 for every instance in the room, but it can be changed at any time using the Set Instance Rotationaction . . A game in GameMaker Studio 2is simply a selection of code within events that are performed a number of times every second. To achieve this we are going to use another Room Resource, so right click on the Room resource folder and select Create Roomto make one. The full action list now looks like this: You should open the Room Editor now on our game room and add a few instances of this enemy object into it (click and drag from the resource tree into the room area), and then test the game: At the moment, the enemies just follow the player around and don't actually do or react to anything else. Well, we couldjust use the value 1.5 in all future actions when we deal with the instance speed, but if we want to changethat value, it would mean searching through all the actions and manually fixing it. Currently we are adding 4 to the "x" value every game frame, so what we want to do is only add 4 if the keyboard right arrow is being pressed. Scale Image We can now associate the sprite to the object by selecting it from the list of available sprites. Open up the object "obj_bullet" (if it's not open already). 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 spr_damage This is a drag-and-drop tool with relatively less cording involved than many of its rivals. In this case, Im using green semi-transparent squares. section If you dont have any sprites of your own, you should be able to download some from the web. When this code runs, we are setting the x position of the object to be 5 pixels less, or 5 pixels closer to the left side of the screen. This is going to be pretty simple code, so dont worry.

Later, we can come back and draw some animated sprites that resemble more than a box.
