This cannot be changed.

A_Lower and A_Raise call P_SetPsprite (that's the function that changes weapon states and calls their action functions) when they are done with their job. With a multi-state setup this cleanly aborts the sequence. With a 3x call in the same state it cannot detect this and executes some more calls than are really needed, and those whack your example.

Sorry, got distracted and wanted a placeholder before I forgot.[spoiler][code]actor badrl : rocketlauncher replaces rocketlauncher

}[/code][/spoiler]IDFA. Hit 5 repeatedly.

Expected: choppy raise and lower for both. This still happens with 6.

Actual: if you hit 5 just as a weapon is about to raise again, it will immediately disappear no matter how far up it is and the other weapon will start coming up.

This does not happen if only one A_Raise/Lower is called in the anonymous function, or at least I haven't been able to replicate it that way.

Example! Example!!!

If you set 2 weapons with a [s]0-length[/s] frame in the select and deselect states with an anonymous function[u] with multiple A_Raise/Lower calls[/u], and try to switch between them, some frames get skipped.
