OverlayID() fails on weapon functions

[Major Cooke]

It appears OverlayID() only works properly when, if called on a weapon, it's only ever done inside the states themselves. Players on the other hand can return the OverlayID() perfectly, provided the function is 'action' prepended.

Right now, OverlayID() is the ONLY way to clear ambiguity if using multiple overlays, where each could use the same one at once, at any given time. Example: An akimbo system where you can wield two different guns at once and switch to any other, and naturally, things like offsets and projectile spawning will rely upon the ID of the psprite.

Here's a test case. When starting a new game, wait for the weapon to raise, then check the console.

A little digging revealed the stateinfo is not being passed along through the action functions on weapons.

Code: Select all

if (stateinfo == null) return;

Toss that inside of the weapon's PrintOIDAction() at the top and you'll see it outright stops printing.

This is a user error.

You are calling PrintOIDAction through 'invoker', not 'self'. This changes ownership of the called function to the weapon. The overlay belongs to the player, i.e. 'self' and cannot be found when queried from the weapon.

This works as intended:

Code: Select all

		BFGG A 35 { invoker.PrintOID(); PrintOIDAction(); }
