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

[Russel]

Jax created a...unique workaround once that was used for numerous features in CSCC.
Basically, when the player was damaged by a damagetype, they spawned an actor that called A_GiveToTarget to give the struck player an item that would then call A_GiveToTarget to give an item to whoever hit said player.

No one is sure why it works as reliably as it does, but I guess because it adds a delay between the player getting hit and then trying to look for a target.

NeverMind, I think I can make it work.

How Do I make a weapon have a cooldown time?

[Russel]

Under normal circumstances, you would simply want to increase the number of tics used at the end of the firing state, though that may not be what you're asking. Do you want to be able to switch weapons with this cooldown in progress or do you want the weapon to remain selected? The latter is simpler than the former.

[Jdude330]

The Latter, I am trying to make a move that can't be Immediately used over and over.

[Ceridran]

I think you would just have to mess with ammo regen stuff and jumpif lines. You're probably going to want the second thing in this post from Gummywormz.

There are a few options. Most actually define ammo regeneration in the class' weapon. The easiest method is to stick on ammo regeneration to the ready state of the weapon like so.

Code: [Select]

TRHU A 3 A_WeaponReady
COOW B 0 A_GiveInventory("BlueFireAmmo",2)
//it's important to stick your wait time on the A_WeaponReady part and not the A_GiveInventory part because otherwise your weapon will only fire some of the time

The downside is that you have to not fire your weapon to get ammo. Viz implements his ammo regen through a flash state like so.

Code: [Select]

Ready:
OBUS A 0 ACS_ExecuteAlways(998,0,600)
OBUS A 0 A_GunFlash

...

Flash:
TNT1 A 0 A_JumpIfInventory("VizPadTimer", 1, 2)
TNT1 A 0 A_GiveInventory("VoltLaserAmmo", 1)
TNT1 A 35
loop

Calling A_GunFlash enters the "Flash" state. This is where ammo regen occurs, independent of movement or firing your weapon. Ammo is always regenerated.

Hey, so I'm trying to make a projectile that when it hits it's target, it throws both the user and the target in the direction the user is facing. (I also plan on doing one where it's the same, but they go backwards.) I tried some stuff with damagetypes and A_ChangeVelocity, but it didn't work out.

[Korby]

Does that include pitch, or do you only want horizontal movement?

Will the person hit just copy the shooter's momentum, going the same direction, or will it try to go where the guy is facing, similar to Copy Vision?

[Russel]

I feel like something like this can only be done through ACS...specifically Arthur's shield in GVHBDM that does something similar where it shoots a projectile that throws the player it hit in the direction it was travelling if you want to use that for reference.

What are the units used to measure radius and height? And, uh, what's scale used for?

[Ceridran]

Scale affects the size of the sprite itself, as opposed to the entity, which is decided by radius and height. What units are used, I don't actually know.

[Russel]

The units used for height and radius are in map units. For reference, an airman tile is 32 map units in width, which is twice the tile's width in pixel.

[TheDoc]

Thanks.

Also, I can't seem to get this operator working:

Code: [Select]

SPAR A 1 A_FaceTarget
WSPA D 0 A_JumpIf(floorz-z!=0,1)
WSPA D 7 A_ChangeVelocity(8.0,0.0,11.0,CVF_REPLACE|CVF_RELATIVE) //Jumping line
WSPA D 0 A_JumpIf(floorz-z==0,"AttackChance")specifically this second line

Code: [Select]

WSPA D 0 A_JumpIf(floorz-z!=0,1)Instead of skipping the third line and moving to the fourth while the actor is airbourne (because floorz-z does not equal 0), the script keeps going on to the third line anyways, resulting in a never-ending cycle of jumping. Am I using the "!=" operator wrong?

[Russel]

No, "!=" is correct, it means not equal to.
try z-floorz
subtract actor height in space from the floor height in space to get the distance between the actor and the floor.

[TheDoc]

I copypasted it from something else, but didn't think to change it bcuz I didn't think it would make a difference so long as it wasn't equal to 0.

But no, it didn't work.
