A Christmas present for ZDoom

[deathz0r]

This stuff is hot, but I wonder about the following in Graf's example:

Code: Select all

CHGG A 10 A_CustomPunch(5000, 1, 0, "Blood") 
CHGG A 0 A_FireCustomMissile("IceBall", -20, 0, -10, 10)

Can anyone explain what those numbers do? I've assumed that 5000 is melee damage, but I'd rather be certain.

EDIT: Ok, the fourth number in the second line is obviously missile height, still trying to figure out the rest.

EDIT 2: Trying this code out, I made a weapon that shoots ice grenades. However, the projectiles that spawn from the powered-up grenade aim vertically at the player. Here's the code:

Code: Select all

actor SuperIceGrenade
{
	Radius 12
	Height 8
	Speed 20
	Damage 10
        +NoBlockmap
        +LowGravity
        +ActivatePCross
        +ActivateImpact
        +NoTeleport
        +DropOff
        +Missile
	+DoomBounce
	+IceDamage
	ExplosionDamage 128
	ExplosionRadius 128
	SeeSound "weapons/rocklf"
	DeathSound "weapons/rocklx"
	States
	{
	Spawn:
		MISL A 8
		Loop
	Death:
		MISL B 8 A_Explode
		MISL C 0 A_CustomMissile("SuperIceGrenade2",8,0,0)
		MISL C 0 A_CustomMissile("SuperIceGrenade2",8,0,36)
		MISL C 0 A_CustomMissile("SuperIceGrenade2",8,0,72)
		MISL C 0 A_CustomMissile("SuperIceGrenade2",8,0,108)
		MISL C 0 A_CustomMissile("SuperIceGrenade2",8,0,144)
		MISL C 0 A_CustomMissile("SuperIceGrenade2",8,0,180)
		MISL C 0 A_CustomMissile("SuperIceGrenade2",8,0,216)
		MISL C 0 A_CustomMissile("SuperIceGrenade2",8,0,250)
		MISL C 0 A_CustomMissile("SuperIceGrenade2",8,0,288)
		MISL C 8 A_CustomMissile("SuperIceGrenade2",8,0,324)
		MISL D 8 A_Explode
		Stop
	}
}

A_CustomPunch(damage, dontrandomize, useammo, pufftype)
A_FireCustomMissile(type, angle, useammo, xy-offset, spawnheight)


And please don't expect any useful documentation unless this has actually been added to ZDoom. And even then it's up to Randy to change it if he doesn't like parts of it.

Excellent, now I have something to do for a few days.

That's not the problem I'm having. The projectiles that are spawned from the explosion vertically aim towards players. That's a bug (hopefully not related to Chiv's changes) that should be sorted out. If I had any brains on how to code, I'd compile my own version of 96 using Graf's diff and find out if it still happens.

Thst's not a bug. That's a result of improper use of A_CustomMissile. Each missile stores its originator in the 'target' field. But that's exactly what A_CustomMissile has to aim at to work under normal (i.e. a monster attack) circumstances. Plus, changing it might break some existing DECORATE stuff.

[Chilvence]

Ah, I see, you want to make a ring of ice projectiles. If you can squeeze an extra parameter into A_CustomMissile, then why not have an "ignore target" switch on the end? Or does decorate have to specify exactly the right amount of parameters?

[HotWax]

Perhaps this calls for an entirely new special, since it seems alot of people are running into this problem with A_CustomMissile. Perhaps A_MissileNoTarget("missiletype", spawnheight, spawnofs_xy, angle_horz, angle_vert), and maybe even a A_MissileAimRandom("missiletype", spawnheight, spawofs_xy) which would pick random values for the last two parameters?

[Chilvence]

Actually, I remember I wanted an A_TossRandom before for something, but it was forgotten about. They're both simple, but will they be added if I do them?

Really, it seems like every day we want more of the Zdoom pie . Maybe that cvs place would be handy right now...

Just write them and create a .diff to the files in the first post.

Yes, that would be good. Perhaps with A_MissileAimRandom there could be some other parameters to define the range of randomness like (hlow, hhigh, vlow, vhigh).

We already have the aim parallel parameter to control whether missiles would aim at a target or go along their own horizontal paths, so why not have a vertical control as well?

We do? Well then, at least deathz0r should be able to fix his ice grenade thing for now. How do you use it?

[Graf Zahl]

It won't help. All it does is to aim all missiles parallel to one starting at a height of 32. The aim at the target remains the same, jusr with a z-offset.

[randi]

I'm stickying this for the time being so that it doesn't get lost.

[deathz0r]

Hmm, this is weird:

It also happens with the other new weapons I've made, but here's the DECORATE stuff for this particular weapon. What could be causing it? And before anyone even bothers saying the obvious, it is graphically offset correctly.
