A_SeekerMissile not functioning in GZDoom

[MoustacheManny]

I wanted my custom monster to fire seeking missiles so I added the function A_seeker missile at the end just like i saw in other wads but when i booted up the game an error messege came up that said " line 656: Sprite names must be exactly 4 characters'' Any help you guys could offer?
 

 

 Spawn:
        A011 A 0 NODELAY ThrustThingZ(0,random(6,10),0,0) A_SeekerMissile(10,10,SMF_PRECISE)
        loop

You cannot have both ThrustThingZ and A_SeekerMissile attached to single frame like this.

Either spread them to two separate frames, or make an anonymous function that combines them.

 

Also 0 duration looping frame will most likely totally freeze or crash the game.

Thank you.

Do you know how I would arange them to be on different frames?

This is what you currently have:

 

 Spawn:
        A011 A 0 NODELAY ThrustThingZ(0,random(6,10),0,0) A_SeekerMissile(10,10,SMF_PRECISE)
        loop 

This is what it should probably look like:

 

 Spawn:
	A011 A 2 A_SeekerMissile(10,10,SMF_PRECISE)
	loop 

Note that "ThrustThingZ" is not a valid DECORATE action function, so you cannot use it in your missile's definition. If you would like to modify its upward velocity, you will need to use an actual action function, like A_ChangeVelocity. To apply it to a separate frame, simply add another frame to the state definition:

 

 Spawn:
	A011 A 2 A_SeekerMissile(10, 10, SMF_PRECISE)
	A011 A 2 A_ChangeVelocity(0, 0, 10, CVF_REPLACE)
	loop

It Almost worked but now instead of throwing the projectiles forword he throws the straight up

[ramon.dexter]

What do you think, the ThrustThingZ() does?

[MoustacheManny]

When I was using ThrustThingZ It worked fine because I copied and pasted that function and values fron another wad that i liked. Im just not sure how to edit the A_ChangeVelocity function to have the same results.

Yeah, typical. Blind copy of other mod without trying to understand what the copied does.
