Invisible wall , level borders

nzervu · Post by **nzervu** » Fri Sep 04, 2009 10:58 am

To create my level/map bordes I would like to create invisible walls, so that models collide with it and will not be able to walk further.

Any suggestions? Thank you in advance

And something else.. I want to create a rails texture in 3dsmax. Is there a way to make it semi-transparent?
like below, where white is transparent...

For your first question, model your invisible wall, and then make a 100% black texture for it, then set that as the texture for your invisible wall mesh, then set the material type to EMT_TRANSPARENT_ADD_COLOR.

does setVisible(false) work in this case?

for that, you have to make difference in your loader algorithm.
i suggest you to make it transparent texture, and just give a full transparent texture xD

or if youre making the whole map in one model, then that would be a good idea to use a different model for collision.
you know, one model for displaying, and one more, more primitive model what not shown, but used for collision

You could also make an animator that limits the position of the camera to be inside of the bounding box of the terrain. Doing anything that renders transparent, or semi-transparent geometry would be a bad idea.

You could also just add the box to a collision mesh, and set that as the mesh for the collision animator. This way you wouldn't have to draw anything

what you are saying is just good for squared maps.
but what about if you make an island, and dont want to let your player to jump into the water?
dunno what does he want to achieve thou
