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

You're not defining a source buffer, so this ...

CopyRect 0,0,128,128,0,0,0,TextureBuffer( radtex )

Should be this ...

CopyRect 0,0,128,128,0,0,backbuffer(),TextureBuffer( radtex )

This should have no effect on collisions but if you need help with that post your definitions etc... or some working code.

actually I fixed it. It was a problem with the hiding and showing of the "cam" camera, for some reason it hid it when the collsions happened or something. but thanks for the help.

Hiding an entity will erase its collision stack, maybe this was the problem. You may also use CameraProjMode to deactivate a camera temporarily

thanks jfk.
any comments on the code are welcome cause i have no clue if this is correct. it just works, mostly.
