Scriptable weapon action?

[Ty Halderman]

I'm pretty sure I know the answer to this, but is there any way to trigger a script when a weapon is fired? This is generic, such as let's say I put a weapon in slot 8, and I wanted to script what happened when it was fired vs. using DEH/BEX to specify "normal" code pointers.

Assuming I'm right and that isn't possible, I guess the best alternative would be to bind a key to the script as the "how to use this weapon key." But then I'd need to know which weapon the player was holding at the time, and I don't know of a way to query that--it's not a usual APROP sort of question, I don't think.

A cookie to whoever proves me wrong

You are right, it's not possible to execute a script in a code pointer (because that's what you want) But you can check which weapon the player is using with the CheckWeapon(weaponname) function.

If it was a weapon that fired a projectile that Zdoom can use for Thingcount, you could have a thing count script running, then as soon as your projectile appeared, you could do stuff.

Hmm... sacrificing one monster or Doom object, say the Candle, and whenever it appeared in a level, a script that loops every tic would spawn a projectile for ever count that it's there. The candle would then self-destruct and be gone in the next tic.

Only question now, is how to spawn it at the player(giving the players unique TIDs should work there), and having it fire at the same angle the player facing, both pitch and yaw..

Actually CheckWeapon() (the syntax you gave is for SetWeapon) but I didn't know it existed in the first place. Perfect.

I can do that. And I can make that projectile invisible, so it's only programatically that it even exists while being looked for.

For what I've got, I don't really need it to act like a weapon, more of a control device. I can use ACS trickery to make the effect what I want it to be, now that I'm in charge .

From looking at the source CheckWeapon requires a weapon name as parameter and returns either 1 or 0 depending if the selected weapon is the one specified by name.

Oops, right you are. I didn't notice the STACK(1) = 0 == strcmp... construct, just that STACK(1) was being set to something. Thanks.
