[Solved] Finding the Terrain Object in a Scene

[Shard]

How do I get a pointer/reference to the terrain in a scene?

I need it so that I can check terrain normals when doing my AStar scan function.

I did exactly that, and at the time of that thread, it worked.

I did it again earlier today and it didn't work; I got a null pointer.

 

I was thinking that something in the code had changed.

My code is below.

 

	int childCount = scene.GetCountChildren();
Entity ent;
string className;
string objectName;
string childClass;
TVec3 objectPos;

for(int i = 1; i < childCount; i++)
{
	ent = scene.GetChild(i);
	className = ent.GetKey("classname");
	objectName = ent.GetKey("name");
	objectPos = ent.GetPosition();
	childClass = ent.GetKey("class");

	if(childClass == "Terrain") aStar.terrain = ent;
	if(objectName == "node_1") nodeOne = objectPos;
	else if(objectName == "node_2") nodeTwo = objectPos;
	else if(objectName == "waterplane_1") aStar.waterHeight = objectPos.Y;
}

You can see how it's done in gamelib.cpp, and use it or copy it.

I did take a look at it and looked just like my code.

Yet my code doesn't work.

Any thoughts?

 

			if( (es=="nothing") && (cl=="Terrain") )
		{
			// printf("******** FOUND TERRAIN ********\n");
			terrain = e;
			SetEntityKey(e,"status","handled");
		}

I found the bug and fixed it.

 

From:

 for(int i = 1; i < childCount; i++)

 

To:

 for(int i = 1; i <= childCount; i++)

 

 

Yep, since the terrain is the last object in a sbx, I always missed it because I wasn't checking the last element.
