Welcome to the GMEdit wiki!
Check out the "Pages" section on the right side.
Here's a small breakdown of additional language features that GMEdit offers on top of GML:
Feature | What you can do | Instead of what |
---|---|---|
#args |
#args a, b
// optional arguments:
#args a, b = 4, ?c
|
var a = argument0, b = argument1;
// optional arguments:
var a = argument[0];
var b = argument_count > 1 ? argument[1] : 4;
var c = argument_count > 2 ? argument[2] : undefined; |
#import |
#import variable_instance_get as v_get
var v = v_get(self, "some");
// multiple items:
#import scr_some_package.* as Pkg
Pkg.one(1);
return Pkg.two(2); |
// [transformed to in saved file]
var v = variable_instance_get(self, "some");
// multiple items:
scr_some_package_one(1);
return scr_some_package_two(2); |
types |
var v:Grid = new Grid(4, 4);
v.set(0, 0, "hi");
var r = v.get(0, 0); |
var v = ds_grid_create(4, 4);
ds_grid_set(v, 0, 0, "hi");
var r = ds_grid_get(v, 0, 0); |
inline functions |
on_click = #lambda { trace("hi!"); }
on_destroy = #lambda { trace("bye!"); }
|
on_click = scr_obj_test_on_click;
on_destroy = scr_obj_test_on_destroy;
// ... in scr_obj_test_on_click:
trace("hi!");
// ... in scr_obj_test_on_destroy:
trace("bye!"); |
coroutines |
/// array_foreach(array)
#gmcr
var arr = argument0;
var len = array_length_1d(arr);
for (var i = 0; i < len; i++) {
yield arr[i];
}
// used like:
var iter = array_foreach(0, myarray);
while (array_foreach(iter)) {
show_debug_message(iter[0]);
} |
- Smart auto-completion
- Types
- JSDoc tags (incl. additional ones)
- @hint tag (mostly 2.3)
- `vals: $v1 $v2` (template strings)
- #args (pre-2.3 named arguments)
- ??= (for pre-GM2022 optional arguments)
- ?? ?. ?[ (pre-GM2022 null-conditional operators)
- #lambda (pre-2.3 function literals)
- => (2.3+ function shorthands)
- #import (namespaces and aliases)
- v:Type (local variable types)
- #mfunc (macros with arguments)
- #gmcr (coroutines)
