LinePick problem

I want that spheres don't cover the boxes. I try to use linePick but it doesn't work. Anyone knows? Is it because i don't use correctly the function or there's another problem?

Thanx

FYI, What are the forum codes?

You just didn't have your linepick command set up correctly. That's the only line I changed.
Since your cubes are at Z position -.25, I set the line pick to check from -1 to 0.
I also set it to have a radius of .05 to account for the radius of the sphere.

Function createxCibles(nb%)
	Local e 
	For i%=0 To nb%
		k% = 0
		c.TCible = New TCible
		c\typ% = typ%
		c\entite = CreateSphere(16)
		ScaleEntity c\entite,.05,.05,.05
		EntityType c\entite,TYPE_CIBLE
		EntityColor c\entite,100,100,180
		EntityRadius c\entite,.05
		NameEntity c\entite,Handle(c)
		
		Repeat
			; e = 0 
			c\x# = Rnd(-2,2)
			c\y# = Rnd(-2,2)
			; 
			e = LinePick(c\x#, c\y#, -1, 0, 0, 1, .05)
			
			If e <> 0 Then 
				DebugLog("move !!!" + k%)
				k% = k% + 1
			EndIf
		
		Until (e = 0)
	PositionEntity c\entite,c\x#,c\y#,-.5 
	Next


End Function

This basically works.
However, it doesn't take into account the fact that one of the cubes is rotating.
An easy fix for that could be to place a sphere/cylinder with the same radius as the cube at the rotating cubes position (with the same entitytype) while placing the small spheres, and then erase it later.
