Is there any hitscan laserbeam-like function that has autoaim?

[Slayer777]

Code: Select all

	bool A_FireFragment(Class<Actor> projectile, double angleRange = 360, double vrange = 90, int numRays = 60, double distance = 512)
	{
		for (int i = 0; i < numRays; i++)
		{
			FTranslatedLineTarget t;
			double an = angleRange/numRays * i;
			double pitch = self.AimLineAttack(an, distance, t, vrange);
			if (t.linetarget != null && t.lineTarget != target)
			{
				vector3 offset = Vec3Offset(0, 0, 0);
				SpawnMissileXYZ(offset, t.lineTarget, projectile, true, target);
				return true;
			}
		}
		return false;
	}

Using SpawnMissileXYZ because it looks like SpawnMissile only launches from 32 units up.

The reason it does that is because you didn't add an offset on the Z axis, so the projectile flies from the actor's feet to the target's feet.
I assume you want the projectile to fly from the actor's feet to the enemy's center?
I am certain there is a better way to do this, but try this code:

Code: Select all

vector3 offset = Vec3Offset(0, 0, 0);
let proj = SpawnMissileXYZ(offset, t.lineTarget, projectile, true, target); //Cast the projectile to a pointer
proj.A_Stop(); //Stop the projectile
proj.Vel3DFromAngle(proj.speed,proj.AngleTo(t.lineTarget),proj.PitchTo(t.lineTarget,0,t.lineTarget.height/2)); //Aim it at the monster's center and fire
