random gibbing chance with chaingun

[occultfactory]

I'm new to programming stuff. I did my best to study Zdoom wiki and read articles about damagetype and A_jump.

I wanna make 2 types of puffs, one with normal puff and the other one with damagetype Extreme (+Extremedeath doesn't work for this actor, idk why).
I learned that A_Jump(127 gives 50% chance to do (?) something...
Also which file should I define damagetype? Wiki says MAPINFO has it but I can't find damagetype declaration within MAPINFO.

Just don't know how to put them in the below code. Somebody please help...

Actor ChaingunPuff : HARPuff
{
+ALWAYSPUFF +FORCERADIUSDMG
DamageType "Chaingun"
States
{
XDeath:
Melee:
Spawn:
"----" A 0 A_FaceTarget
"----" A 0 A_Warp(AAPTR_DEFAULT,5,0,0,0,WARPF_NOCHECKPOSITION)
"----" A 0 A_JumpIfInTargetInventory(MTurretLoad,1,"Super::Spawn")
"----" A 0 A_JumpIfInTargetInventory(ChaingunRotationSpeed,0,2)
"----" A 0 A_Jump(256,"Super::Spawn")
"----" A 0 A_JumpIfInTargetInventory(haschainIncendiaryRounds,1,2)
"----" A 0 A_Jump(256,"Super::Spawn")
"----" A 0 A_ChangeFlag(NODAMAGETHRUST,1)
"----" A 0 A_ChangeFlag(BLOODLESSIMPACT,1)
"----" A 0 A_ChangeFlag(NOPAIN,1)
"----" A 0 A_Explode(5,32,0)
"----" A 0 A_SpawnItem(ChainGunIncendiaryFX)
Goto Super::Spawn
}
}

Custom damage types should be included in MAPINFO as it says here. Just make a block inside your MAPINFO lump/file that's called DamageType and inside the brackets, you define the properties you want.

And about the puff.. you shouldn't have it doing that. A puff should only be for displaying something on colission, and playing specific impact sounds, or specifying a damage type for your hitscan weapon. Making a puff do complex stuff like that will end up having unintended side effects. If you want your puff to have a random chance of gibbing, you should define a "clone" puff with the +EXTREMEDEATH flag, and have your weapon fire it with a random chance. Also try making your weapon do all those complex actions in its firing states instead.

Thank you so much! If you don't mind... can I get an example code? Also, +EXTREMEDEATH doesn't work on some puffs.

From my mod here. You can check the code by opening Qua.pk3, and going into QuakeW/Weapons/Machinegun.txt.

This is what I used in the Machinegun firing definition (it's ZScript, that's why the syntax is different, but DECORATE should work very similarly):

Code: Select all

	Fire:
		TNT1 A 0
		{
			A_PlaySound ("q2mgun/fire", 5);
			A_GunFlash();
			A_SpawnItemEx ("GunLightFlash", 0, 0, 0, vel.x, vel.y, vel.z, 0, SXF_TRANSFERPOINTERS);
			if (CountInv("PowerWeaponLevel2"))
			{
				A_PlaySound ("quad/fire", CHAN_WEAPON);
				A_FireBullets(3,3,-1,32,"SuperMGPuff",FBF_USEAMMO|FBF_NORANDOM);
			}
			else
			{
				A_FireBullets (3,3,-1,8,"MachinegunPuff",FBF_USEAMMO|FBF_NORANDOM);
			}
			if (invoker.user_machinegunvalue > 0)
			{
				if (invoker.user_machinegunvalue == 1)
				{
					return resolvestate ("HandBack1");
				}
				else
				{
					return resolvestate ("HandBack2");
				}
			}
			return resolvestate (null);
		}
		MACH BC 2 Bright;
		TNT1 A 0 A_JumpIfNoAmmo(2);
		TNT1 A 0 A_ReFire("HoldFire1");
		MACH DEF 2;
		TNT1 A 0 A_CheckReload;
		Goto Ready1;

And both puff actors used in this instance:

Code: Select all

CLASS MachinegunPuff : BulletPuff
{
	States
	{
	Crash:
		TNT1 A 0;
		TNT1 A 0 A_Jump (40, "PlayWallSound");
		Goto Super::Spawn;
	PlayWallSound:
		TNT1 A 0 A_PlaySound ("puffhitwall");
		Goto Super::Spawn;
	}
}

CLASS SuperMGPuff : MachinegunPuff
{
	Default
	{
		+EXTREMEDEATH;
	}
}

+EXTREMEDEATH does work on puffs. If it doesn't work for you, then your code must have some errors.
