picking in viewport

Blitz3D Forums/Blitz3D Beginners Area/picking in viewport

atv	(Posted 2013) [#1]

I would like to have a viewport in the righthand side of the screen, how do i do that ? I can get 4 but i can't get just one in the righthand side (half of screen, half of height)

Also, once i do that, picking doesn't seem to work anymore. I currently have:
If PickedEntity()<>0 Then
Text 0,12,"Object selected:"
Text 130,12,EntityName(PickedEntity())

Any ideas?

Have you written CameraPick(PX%,PY%) before the other lines ?
Have you set the appropriate meshes/colliders as pickable ? with EntityPickMode(Mesh,2)

If it doesn't work with several viewports, you can use linepick instead.

Camera = createcamera()
cameraviewport Camera, Graphicswidth()*.5, 0, graphicswidth()*.5,graphicsheight()

If you are then using camerapick with the mouse coords, you will likely need to subtract the graphicswidth() away from mousex() to get the true coordinates for picking.
