Welcome to ZDF!

You're stuck, because "itemuse" (invuse) isn't player input to start with. Inventory usage (and weapon selection by extension) processes the name of the inventory you want to use. This is regardless if it's actually the "selected" inventory or not (see the use ccmd). The invuse key is nothing more ...

Hey, I'm trying to get a ReFire state going for a CustomInventory item to check if the player's holding down the itemuse button.
Unfortunately, GetPlayerInput doesn't have an ItemUse button.

Can I force-map BT_User1 to the itemuse key across players, or am I stuck here?

Thanks!

Is it possible for me to negate the +NoDamageThrust on a player class without resorting to ACS for a specific actor?

Essentially, how would I create an actor that ignores the NoDamageThrust flag on a playerclass?
