It's not a waste of time, rest assured. By default it's naturally implied especially if it's assigned from a weapon.

Thank you for your response. I didn't know that. It does seem to work, although the offsets need re-adjustment. Thanks for your help! Wonder why the Wiki does not state this? Regardless, you can close this thread now. Sorry for your wasting time.

I'm unable to look at the moment, but did you specifically call A_OverlayFlags and set PSPF_ADDWEAPON to false? By default, any overlay created automatically has PSPF_ADDWEAPON included.

Hello. I apologise if this is already known, not a bug, or a mistake on my part. I created a pistol which inherits from a base weapon. Its alt-fire is supposed to perform a kick attack, with some of the frames using A_WeaponOffset including interpolation in order to smoothen the animation. Once a kick attack is executed, an overlay is called, which is supposed to make the weapon look like it's put aside. However, once A_WeaponOffset is called, the overlay's offset changes as well, despite not having the PSPF_ADDWEAPON flag.

Here's an example PK3. Once loaded, please press the Zoom button. It's a reference of how the overlay's offset should normally be adjusted. Now, please press the Alt-fire button. A kick attack will be performed and the overlay will mess up once the A_WeaponOffset function is called.
