EntityVisible() Problem

Hi,

I've run into a slight problem on the level map I'm working on.

I need to put a flare sprite inside a semi-transparent mesh cube in order to make a light fitting.

If the flare sprite is NOT contained within the mesh cube, then I can use the following code to manage visibility:

If EntityVisible(player\camera,flare\sprite)
  flare\alpha = 1.0
Else
  flare\alpha = 0.0
End If

But, if the sprite's centre is inside a mesh - even a semi- transparent one (say alpha=0.5) then the EntityVisible() command treats the sprite as though it is hidden from the camera.

Is there a way around this?

I need to turn off the flares that are fully hidden to the camera, whilst allowing objects behind semi-transparent surfaces to be visible.

Regards,

Rogue Vector

Take a look at the EntityPickMode command which lets you specify whether or not an entity obscures (gets in the way) when using EntityVisible.

It's always fun when you figure it out for yourself. I taught a friend's son the basics of computer programming.

One thing I emphasized to him, was this: a computer does not do what you THINK you told it to do, but what you ACTUALLY told it to do.
