GameMaker function to handle optional arguments?

[Shadowblitz16]

does anybody know if its possible to make a function call argument() that can be used with script mandatory arguments?
maybe just a function for both?

parameters could go like..
-argument index
-optional?

 

[Binsk]

argument0 // Required
argument[0] // Optional
argument_count // Number of arguments passed

If what you meant was extra argument, maybe you can make it yourself? Using global variable, new script, or ... anything else.

So I'm facing this issue too. I'm converting a project from GM1.4 to GM2. I have a script that takes 3 required parameters and then any number of optional parameters. How do I do optional parameters in GM2? I'm getting the below compilation error when I try to run my project. No script errors.

Script: scr_loadPlayer at line 24 : function "scr_instanceCreate" expects 3 arguments, 8 provided

What I want here is to have these optional parameters available in the create event of the object. If there is a better way to do that in GM2 I'm all ears.

Thanks!

That should not have compiled on GMS 1.4 to start with, the system for taking arguments hasn't changed in GMS 2.

If you want to take optional parameters, you must use the array form for arguments (e.g. argument[0] instead of argument0) throughout the script. Mixing the array and non-array forms within the same script is strictly forbidden.
