ZDoom

The function itself has an absolute parameter. It's false by default already, which makes it [url=https://github.com/coelckers/gzdoom/pull/553/files#diff-4c356f5b379e4df1b56377c1c374566fR2061]portal aware.[/url]

I'm having trouble figuring out how to convert Gutawer's code to LevelLocals.SphericalCoords. I'd like to be able to account for portals.

[url=https://github.com/coelckers/gzdoom/pull/553]It looks like it was already added[/url], just no one closed the thread.

Would it even make a performance difference anymore nowadays?

Bumperino. Will this get added natively or will it remain DIY?

Before try to make something like this I wonder does distance(2/3)d more performance wise than cos/sin(arctan(number) )?

I'd rather do this natively for performance reasons.

I've submitted [url=https://github.com/coelckers/gzdoom/pull/553]pull request #553[/url] which, if merged, will do what you need. See [url=https://forum.zdoom.org/viewtopic.php?f=59&t=61745]forum post[/url] for an example.

That is correct.

He's trying to have this be made done on the engine side to reduce calculations on the VM side, correct me if I'm wrong.

Vector3 dirTo = vec3To(other).unit();
double angleTo = atan2(dirTo.y, dirTo.x);
double pitchTo = -asin(dirTo.z);

You can do this via something like this:
[code]
Vector3 dirTo = vec3To(other).unit();
double angleTo = atan2(dirTo.y, dirTo.x);
double pitchTo = -asin(dirTo.z);
[/code]
You can of course take out the angleTo line if it's unnecessary.

[quote="Major Cooke"]Anyway, Matt, one thing you could do in the mean time is use A_Face and set the angle limit to something non-zero.[/quote]That's pretty much what I'm doing now - storing a backup pitch and angle, calling A_Face, recording the new pitch and resetting the pitch and angle.

All defined in zscript, inside gzdoom pack, hitscan enemy use "aim line attack" to get slope/pitch to it target, not arctangent of distance and positions.
So, I think, this is the quickest way to get pitch/slope to some actor.

...What was the point of your post?

Anyway, Matt, one thing you could do in the mean time is use A_Face and set the angle limit to something non-zero.

extend class Actor
{
	void A_PosAttack()
	{
		if (target)
		{
			A_FaceTarget();
			double ang = angle;
			double slope = AimLineAttack(ang, MISSILERANGE);
			A_PlaySound("grunt/attack", CHAN_WEAPON);
			ang  += Random2[PosAttack]() * (22.5/256);
			int damage = Random[PosAttack](1, 5) * 3;
			LineAttack(ang, MISSILERANGE, slope, damage, "Hitscan", "Bulletpuff");
		}
	}
