I'm still having problems with this. I'm not sure what I'm doing wrong. Basically, I want to be able to select stuff in a 3D environment. For example, if there's a tree in the distance, when the mouse cursor hovers over it then the tree will light up or words will come on the screen.

A snippet of what I've done:

Code:

---

text contact_text	
{
  font = standard_font;
  layer = 10;
  pos_x = 350;
  pos_y = 100;
  size_y = 70;
  offset_y = 0;
  flags = center_x, narrow, visible;
} 

string str1 = "The mouse is touching the tree. \n Testing the text now. \n testing the line breaks also! loading.....";



function mouse_test()
{

temp.x = MOUSE_POS.x;
temp.y = MOUSE_POS.y;
temp.z = MOUSE_POS.Z;
vec_for_screen(temp, camera); 



if((temp.x == tree.x) && (temp.y == tree.y) && (temp.z == tree.z))
 {
	contact_text.string = str1;
}
