Hi guys,
I'm just trying to add some trees to my heightmap terrain, but..being new..I am doing something wrong.

//tree
for t=1 to 1000
tree=CreateObjectBox(3,50,3)
x# = random(-3000,3000)
z# = random(-3000,3000)
y# = getobjectheightmapheight(tree,x#,z#) // <<<<< this line I think is the reason.....can anyone shed some light on this for me please?.

SetobjectPosition (tree,x#,y#,z#)
next

Are you sure it should be "tree" in the

getobjectheightmapheight(tree,x#,z#)

command.. and not the terrain object instead? - maybe?

Wow - 1000 tree objects too, the FPS will fail for you- maybe look at mesh memblock work instead when you get used to AGK

OMG, lol..I am such an idiot... literally face palmed myself hehe

THANK YOU!!..

//tree
for t=1 to 100
tree=CreateObjectBox(3,50,3)
x# = random(-3000,3000)
z# = random(-3000,3000)
y# = getobjectheightmapheight(1,x#,z#)
SetobjectPosition (tree,x#,y#,z#)
next

I am on uncertain territory here... but I am using the CreateObjectFromHeightMap command not the CreateObjectFromObject mesh..and it does seem to run ok even with 50000 trees at (35fps)
So far, (I know very little)..I have not investigated mesh culling to save some gpu... but for now. And I am very green at programming. I will have a read up on the link you posted...heck, for now I am just happy to have the terrain and trees working.
Cheers again.
