It should be noted that the execution of the function ends at the return statement , meaning that any code which comes after return has been called will not be run.
Note that if you create a script function with no return value then in your code check for one, you will get the value undefined by default.
To call a script function from within a piece of code, just use it the same way as when calling any runtime function - that is, write the function name with the parameter values in parentheses. So, the above script would be called like this:. NOTE : When using your own functions from scripts in the code editor, you can press or click the middle mouse button on the function name to open the script that contains it for editing directly.
However, you can still call scripts in your game - and you can name scripts the same as a function that you define in them - which can give rise to a issues due to the way that GameMaker Studio 2 stores asset references. To give an example consider this code, called from an instance:. The above code is attempting to call a script called "myscript" within a method, which in this case will fail.
This is because the in-line function is actually using the index for the script asset and not actually calling the script - eg: if the script index resolves to "4", essentially the function is calling 4 arg ; , which makes no sense. The code should instead be structured in one of the following two ways:. This is important to note, especially when working with legacy projects where scripts contain one single function, and the function is named the same as the script.
However, you really should never do this, and your scripts should be named independently of the functions they contain. This leads us to the final and most important thing to know about scripts and the functions they contain: scripts are parsed on a global level and will be compiled at the very start of the game.
This means that technically all functions in a script are "unbound" method variables , and any variables declared outside of a function in the script will be considered global variables.
For example, consider this script:. In the above case, not only have we defined the functions Foo and Bar but also the variable blah and all of them are considered to have been created in the global scope.
Also you can often find information on the event in which you must place the script. Now you need to add some code to execute the script. There are two ways of doing this. The second way is to use scripts. These must be added using GML. If you want to use the Drag and Drop interface of Game Maker then go to the event the code must be placed in.
This usually stands mentioned in the beginning of the script. Within this event add from the tab code the command execute script and drag it to the event. You now get the screen:. At the top of the script stands what the different arguments should be. Fill in the arguments on the places. So if in the script stands: argument0: horizontal speed then fill in area 2 after argument0 : the speed you want to have as horizontal speed. A few notes:.
If you do not need to fill in a certain argument you can leave the field blank. In the cases you need more then 5 arguments or you need to know the value the script returned you can also use a code block for this.
Note that there's no reason to add a code block just to call up a script unless you need these points.
