SetTerrainHeight

C: void SetTerrainHeight( TEntity terrain, long x, long y, flt height )

C++: void Terrain::SetHeight( int x, int y, flt height )

BlitzMax: SetTerrainHeight( terrain:TTerrain, x, y, height# )

Pascal: procedure SetTerrainHeight ( terrain:THandle; x:Integer; y:Integer; height:Single );

Sets the terrain height at the specified grid point. Height should be a number between 0 and 1.

 

How is a height between 0 and 1 of any use? Are all vertex heights in a terrain decimals are they?

I think it's internally a byte with values 0-255, but that would be difficult to use, so 0.0-1.0 is better.

Ah I see. Thanks for the heads up Lumooja.

Internally, it's a word value (2 bytes). The real height is the terrain scale y component times the internal value, divided by 2^16. The GPU has a setting to treat the word as a 16-bit float.
