help with rendering to texture

Blitz3D Forums/Blitz3D Programming/help with rendering to texture

hi I'm having problems with rendering to a texture and collisions.
here's what i got
While Not KeyHit(1)
Cls
If KeyHit(19) Stop;WireFrame True;

updatebul()
updatechar()
;updateenemy()
updatehud()
UpdateWorld
HideEntity cam
ShowEntity overheadcam
RenderWorld
CopyRect 0,0,128,128,0,0,0,TextureBuffer( radtex )
ShowEntity cam
HideEntity overheadcam
RenderWorld

Text 0,0,TrisRendered()+"   ",0,0
WaitTimer(fpstimer)
Flip
Wend
End 


theres my mainloop
and heres my update with the collisions
If EntityCollided(c\e,weapon1)
c\wepf=c\wepf+1
FreeEntity gun4
ShowEntity gun5

the gun is global

If I comment out the render to texture part in the loop it works fine but if i don't it wont detect the collision
but other collisions work fine
the c\e is a camera with a radius of 5
