TerrainY equivalent for mesh terrains by PsychicParrot (Posted 24 years ago)
Simple function to act as a 'terrainy()' for a mesh terrain (or any kind of mesh floor, I guess...) Make your mesh terrain pickable using entitypickmode - in the case of a terrain mesh, you'll use mode 3 for polygon. use: terrainy=getmeshterrainy(entity) So, whereas you pass in the x,y,z to terrainy() - here, you just pass in the name of the entity you want to check under. This function returns the first 'pickable' entity under the entity you pass in... The main line: pick=LinePick(EntityX(ent),EntityY(ent)+20,EntityZ(ent),0,-30,0) has two numbers 20 and 30. This says "start looking for entities at entityy(entity)+20 and stop at -30. This 'projects' a line from above the entity to below it. Change these values to 'tune' to your own world sizes if you have any problems.
Function getmeshterrainy#(ent) pick=LinePick(EntityX(ent),EntityY(ent)+20,EntityZ(ent),0,-30,0) Return (PickedY()) End Function
