Grab/Thrust target towards the caller?

[DnB-Freak]

Hi again, community.
I'm wondering if anyone knows if there's a way for a monster to grab/thrust its target towards it.
The effect consider to be similar to A_RadiusThrust with negative force, but only for one specific target not an environment of targets.
I've searched at the forums for it without any progress.
It can probably be done with ZScript, but I'm in need of an example.

---

Code: Select all

Vector3 thrust = victim.Vec3To(target);
victim.Vel += thrust.Unit() * (255. * 50 / max(victim.Mass, 1));

Didn't work, I'm probably doing it wrong.

How does the correct way look like?

Did you put it in a function and called it at least for couple of frames? If you call it once, it may be not enough to move the target because of the friction. Try something like this:

put some int to store the time spent on thrusting inside actor class

Code: Select all

int ThrustState;
bool IsThrusting;

create some state in which the actor do the thrusting ( )

Code: Select all

States
{

	GetOverHere:
		TNT1 A 1 ThrustTarget(50, 10);
		Loop;
}

the function, I did not look at the wiki, but your calculations seem to be alright

Code: Select all

ThrustTarget(int force, int duration)
{
	if(!target)
		SetState(SeeState);

	if(!IsThrusting)
	{
		ThrustState = duration;
		IsThrusting = true;
	}

	if(ThrustState > 0)
	{
		Vector3 thrust = Vec3To(target);
		target.Vel -= thrust.Unit() * 255.0 * force / max(target.Mass, 1));
	}
	else if(ThrustState == 0)
	{
		IsThrusting = false
		SetState(SeeState);
	}
	ThrustState--;
}

I was trying out the anonymous functions in decorate, but GZD doesn't recognize the math functions as they're for ZScript only.

I had to convert the entire Decorate to ZScript to get this working.

Anyhow, you gave me a solution I find very useful, Thanks
