The "How do I make a weapon do that?" thread

[BiscuitSlash]

Heh heh, this weapon is coming on well! In fact it's just about finished!....except....one more thing....

What exactly is it that makes bots jump when attacking with the weapon? Some sort of BotCheck? I looked in Top spin's coding and couldn't see anything. yes that's right, I care about bots -_-

[Korby]

ACS_Execute(195,0)

This thrusts a bot into the air.

[BiscuitSlash]

Yay! It's done! Thank you to everyone that helped! This weapon was much harder to make than i thought without knowing all those code things. I'm sure Propel Blade and Flame Sword will be easier to make. inb4yes

[Hallan Parva]

I want to make a projectile change directions and start to fly backwards like Shadow Blade, but there's a catch: I want the direction change to be "gradual". This means I want the projectile to slowly come to a halt, then slowly speed up in the opposite direction. I don't want the projectile to just "jump" and start instantly moving backwards like Shadow Blade.

Any ideas on how to do this? :?

[Ukiyama]

Alright I got a new question... in the spoiler I have a weapon I've been working on (if you've played x8 you know where it comes from). I want it to be aimable and have the same velocity as it keeps "growing" in size. (I know its a spawnitemex projectile when it starts but that is just a temp thing so I could test the damage of it).

A_SpawnItemEX doesn't save projectile parenting by default if used multiple times. Try something like this for the SpawnItemEX methods:

SQUE B 0 A_SpawnItemEx("SqueezeBombLevel1",0,5,35,15,0,0,0,SXF_TRANSFERPOINTERS)

So I want this weapon to BLOW users around. That's all in terms of effect. Problem is, it doesn't do the pushing thing and it actually DAMAGES players even when I clearly(?) told it not to do any damage. I looked at the magnet mang class and all but I couldn't seem to figure it out much.

[Gummywormz]

Custom pain states bro. And it needs to do at least 1 damage in order for it to do anything (usually)

[BiscuitSlash]

Ack, I was hoping I wouldn't need to bother with it doing damage. It might defeat the purpose of the weapon.

[Gummywormz]

It's only needs 1 damage. You can even heal the damage in the painstate if you want.

[MasterXman]

I can't make rockcube an item. How do I make it an item? Woof! more MMBN STUFF!

Did this just get ignored?

[Korby]

Look at the game. Stare at it for three hours, then look at where the items are stored and learn.

Also, ZDoom Wiki.

[BiscuitSlash]

Me again! Hi!

There's something really weird with this weapon that I can't understand. For some reason, even when it does (0) damage and there's no custom pain state, it actually DOES damage players. I can't understand why.
Here's the coding for the weapon.

But really, even when set to no damage at all, this thing can take away about 10-40 of your health in one go! (I hope it's not because of the radius thrust -_-)

[Gummywormz]

Because you have +RIPPER set. Which means it's gonna do more than 1 damage to the actor, since it constantly causes damage when going through.
