Weapon won't fire anything
Brixmon:
Someone tell me if posting this many help threads is against the rules or something. As far as I can tell, it isn't...
Soo... now I'm trying to get this weapon to work. It's an invisible weapon meant to work with the Ghast playertype located here: https://forum.blockland.us/index.php?topic=289735
But it doesn't fire anything. The Ghast usually animates properly- its face changes when it's supposed to fire, though sometimes it gets stuck in armAttack and doesn't go back to Root. Even spawning the Ghast Fireball projectile with events works properly- the particles are right, it flies right, and it explodes right.
But no matter how I change it, I can't seem to get it to fire. I have a feeling it's got something to do with the "Charge" state, which is meant to provide a delay before firing to replicate the Minecraft Ghast's chargeup time and give it time to make the sound before firing. But as far as I can tell, it's correct.

Shift Kitty:
Because firing a projectile is supposed to happen in the ::onFire function. You're overriding it and not calling a parent or writing your own projectile spawning code.
It should work if you just add Parent::onFire(%this,%obj,%slot); to it.

I'm... not quite sure where to add that. Sorry if this is obvious stuff.
Scratch that. Saw exactly what you're talking about somewhere else. Thanks!
Edit: So if I don't parent the onFire function, then it completely overrides the default onFire function, but if I add Parent::onFire(%this,%obj,%slot); , it instead adds my code to the existing function? Am I understanding this correctly?
phflack:
Yes, when the function executes it does your stuff, then parent:: stuff tells it to do the old function stuff, then it goes back to your code
Ie
--- Code: ---function thing::onFire()
{
echo("a");
}
function blub::onFire()
{
echo("b");
parent::onFire();
echo("c");
}
--- End code ---
(blub extends stuff)
Would print b, a, c
Also there's nothing wrong with making more topics if they are useful for the discussion of things
