3D Line

Hi.
I am close. I have two balls that are positioned randomly in 3 spaces. Then I make a small square appear between them. Then I scale the square the amount of the distance between the two balls...so far so good. However, the problem is I don't know how to rotate the line in the center to connect to the two balls. I tried pointentity and that doesn't work.

Any ideas?
Thanks!

What happened when you tried PointEntity?

I'm guessing that if you try scaling your square with the line length on a different axis your PointEntity should work.

eg, if your current scaleentity is something like

ScaleEntity lineentity,distance#,1,1

try

ScaleEntity lineentity,1,distance#,1

or

ScaleEntity lineentity,1,1,distance#

I'm not sure which axis PointEntity uses to point but trying them all on the scaling should find it eventually.

here's a nice routine by chroma:

;===========================
;Point Entity at x,y,z
;===========================
Function Point_Entity(entity,x#,y#,z#)
	xdiff# = EntityX(entity)-x#
	ydiff# = EntityY(entity)-y#
	zdiff# = EntityZ(entity)-z#
	dist#=Sqr#((xdiff#*xdiff#)+(zdiff#*zdiff#))
	pitch# = ATan2(ydiff#,dist#)
	yaw#   = ATan2(xdiff#,-zdiff#)
	RotateEntity entity,pitch#,yaw#,0
End Function
;===========================

if it turns out to be pointing 90 degrees away, try scaleing on different axis.

Chroma's function worked! Thanks!

But why didn't pointentity work? I tried scaling on all different axises.

I'm not sure why pointentity doesn't work. But oh well. Chroma's function is more flexible anywho.
