How to find the height at a point in the TerrainSceneNode

MindGames · Post by **MindGames** » Mon Oct 17, 2005 2:43 am

I want to be able to add scene nodes to the terrain scene node but I need to know what height the terrain is at the point I am to add them so that they are not flying or below ground.

Anyone know how to do this? Is this one of those things not yet converted over?

If it isn't converted, what is the C++ method so I can just convert it myself.

Thanks for your help

are you using an fps camera?

Why dont you just take the z value of the camera, and that will give you the height that the camera is currently at?

i think you have the x and z value of the terrain (the ground) and you want to have the height of the terrain at this position?

Then you easily can use the GetCollisionPoint Function... Look in the documentation how to use it...

Guest - No I am not using an FPS camera. I have a camera flying over the terrain. That part mostly works ok. I am doing a strategy game with a 3D map and lots of units wandering around under the control of the AI

Thorben - Thanks, that was what I was looking for. I will give that a try. Do you know how fast it is?
