General

• The extension is now built for LTS2026.
  You can still use it in LTS2022 if you downgrade it using the Project Tool.
• The documentation has been updated to cover a few more stumbling points.
• The extension’s internals have seen some rewriting over the past year, but hopefully nothing that breaks anything for you as the end user.

Novelties

• Added a code_is_live macro that indicates that the script is currently running a live-reloaded version, used like if (code_is_live) { ... }.
• Added live_constant_add_multi(const_struct) for convenience.
• Added notes on self/other flags in live_function_add.

Tweaks

• Added LTS2026 function definitions and macros.
• Particle System assets can now be referenced in “live” code.
• The extension will now inform you if async_load is missing instead of crashing, but this usually means that have other code destroying things that it shouldn’t be.
• Argument count mismatch errors are now reported more properly.
• gmlive-server is now aware of LTS/LTS2026 folders when using shader reloading.

Fixes

• Fixed struct.method(func()) compiling incorrectly.
• [$ has been matched to current GML and no longer shows warnings about ambiguity.
• Fixed live_method(_, undefined) not using the current self
• Fixed macros defined in “live” code sometimes not working
• Fixed incorrect bbox mode being applied to live-reloaded sprites

Constructors in particular

• Values are now allowed in inherited constructor calls (function ctr() : parent(true) constructor {})
• Having ctr = function() : parent() constructor {} is now allowed

Note that both constructor inheritance notations are supported for live-coding constructors and their methods, like so

function CoolThing() : Parent() constructor {
	static fun = function() {
		live_name = "CoolThing.fun";
		live_auto_call
		// ...
	}
	// ...
}

but will not work for stranger things like this:

function FactoryOfFactories() {
	live_auto_call;
	return function() : parent() constructor {
		// ...
	}
}

Which, however, have rather limited use in current GML as we don’t have closures.

1.0.79a

A few more things that I almost forgot about

• Built-in enums (e.g. AudioEffectType.Delay) are now auto-exposed to live code
• There are now functions (live_enum_add, live_enum_add_constant) to add other enums/constants if you need that
• { new X(); } is now a valid statement
• Added a note to documentation on having to re-enable instance_change for room reloading.
