here's one I made, works really nice, and very simple..
if you want, you can use sliding collision for the camera to keep it from going through walls if you want.

it's a lot like DB's "Set camera to follow command"
the 'point' flag at the end will also point 'e1' at 'e2' if set to 1

Function Curve#(d#,c#,s#)
	If Abs(d-c)<0.01
		Return d
	Else
		Return c+((d-c)/s)
	EndIf
End Function

Function followEntity(e1,e2,angle#,dist#,height#,speed#,point=0)
	x# = EntityX#(e2)+(Sin(angle#)*dist#): y# = EntityY#(e2)+height#: z# = EntityZ#(e2) - (Cos(angle#)*dist#)
	PositionEntity e1,curve#(x#,EntityX#(e1),speed#),curve#(y#,EntityY#(e1),speed#),curve#(z#,EntityZ#(e1),speed#)
	If point Then PointEntity e1,e2
End Function

Use:

followEntity(camera,player,entityyaw#(player),100,200,10,1)
