A problem with Thing_Projectile and Spawn

[Caligari87]

I'm working on a "bullet shells" weapons mod that ejects shells from your weapon when you fire. I had it working for a while, with a thing_projectile script that threw shells out onto the ground when the weapon fired. However, there was a problem: the shells spawned at the player's feet, so I decided to get the player's x,y,z and spawn a mapspot at the player's height +40 or so, and then launch the shells and remove the mapspot until the next loop. However, now the shells just fall straight to the ground in the center of the player's sprite. I know the script works, just btw, so no need to ask for it. Is there any way to thing_projectile relative to the player's height???

Also, I want the shells to fly out at a 90-degree angle to the player's view. Is there any way to get the player's angle also?

Please, people. If you don't care, just say so, don't leave me hanging.

Give the shell the NOCLIP flag. If you spawn it inside the player it can't move anywhere.

If I use NOCLIP, it'll go through walls. I want it to bounce. And before, I was spawning it at the player's tid, and it worked fine, apart from being too low.

EDIT: I tried offseting the spawned mapspot outside the player and it did the same thing. When it does work though, it's a cool effect. I'm making a Halo weapons mod to go with this also.

Post your script. Maybe it's just a stupid little error...

[Caligari87]

I fixed the script. It was just a math issue with the z value, but here it is anyway.

Code: Select all

script 1 enter	{
	Thing_ChangeTID(0,500);
	int ammo1,ammo2;
	int x,y,z;
	while(1==1)	{
		ammo2=ammo1;
		ammo1=CheckInventory("Clip");
		if(ammo1<ammo2)	{
			x=GetActorX(500);
			y=GetActorY(500);
			z=GetActorZ(500);			
			Spawn("MapSpot",x,y,28*65536+z,501,0);	
			Thing_projectilegravity(501,random(254,255),0,random(8,15),random(8,15));
			Thing_Remove(501);
		}
		delay(1);
	}
}

The real problem is the code for the bullet shell. It works fine now, but it doesn't bounce, and the death is obviously jury-rigged. If I set it to be a projectile type, or +MISSILE then it "dies" whenever I spawn it, because the player is right nearby.

Code: Select all

Actor shell1 20001	{
	spawnid 255
	speed 10
	radius 1
	height 2
	mass 100
	scale .1
	deathsound "shell1"
	+teleport
	+doombounce
	+floorclip
	States
	{
	Spawn:
		PBUL A 35
		goto death
	Death:
		PBUL B 250 A_Scream
		Stop
	}
}

Also, to repeat an earlier question, is there any way to get the player's angle beyond rough speed checking? That's just not precise enough for my purposes.
