Get Terrain from Scene

[DanielW]

Hi

 

Can anyone explain me how i can get the Terrain Entity out of my Scene in C++ ?

 

Regards Daniel

It's the first entity, so GetChild(scene,0) will return the terrain entity. You can also use FindChild("terrain"), but it's slower.

when i use GetChild(scene,0) my game quits and FindChild(scene,"terrain") is not finding anything

I just looked at gamelib, and there I get the terrain in 3 steps:

 

e=GetChild(scene,i);

...

cl=GetEntityKey(e,"class");

...

 

if( cl=="Terrain" )

{

// printf("******** FOUND TERRAIN ********\n");

terrain = e;

SetEntityKey(e,"status","handled");

}

Ok have tryed this:

 

TTerrain terrain;
TEntity scene=LoadScene("scene/scene1.sbx");	   
int i;
for(i=0;i<CountChildren(scene);i++)
{
 TEntity e = GetChild(scene,i);
 str cl = GetEntityKey(e,"class");
 if(cl=="Terrain")
 {
 terrain = e;
 SetEntityKey(e,"status","handled");
 }
}

 

when i try to debug its still quits while its loading

Make sure you scene variable is valid. I normally use the abstract system like "LoadScene("abstract::scene1.sbx") and scene 1 can be anywhere in your game dir and it'll find it and load it.

Use string, not str for cl. str is just unsigned char*, and does not support == comparison.

I recommend to copy paste shamelessly any code from gamelib, because it just works and is tested. If you can do it better, please do so, but it won't be tested, unless you test it yourself

its still dont working when i delete GetChild elverything Loads but with it it starts Loading elveryting and then quits whitout any message or error.

 

didnt know of the gamelib in the assetstore will give it a look thanks

 

edit: in my scene i have only the Terrain an Atmosphere and light do i need there something more ?

k have found the Problem GetChild should start at 1 not at 0. thanks for the help ^^
