Unigine.GameIntersection Class

Stores the result of the Game.getIntersection() function: the point where the intersection with an obstacle has been occurred.

The following example shows how you can get the intersection point (vec3) of the cylinder between two points with an obstacle. In this example we specify a cylinder from the point of the camera (vec3 p0) to the point of the mouse pointer (vec3 p1) with the specified radius. The executing sequence is the following:

  1. Define and initialize two points (p0 and p1) by using the Player.getDirectionFromScreen().
  2. Create an instance of the GameIntersection class to get the intersection point coordinates.
  3. Check, if there is an intersection with an obstacle. The Game.getIntersection() function returns an intersected obstacle when the obstacle appears in the area of the cylinder.
  4. After that GameIntersection instance gets the point of the nearest intersection point and you can get it by using the getPoint() function.
Source code (C#)
// AppWorldLogic.cs

/* ... */
// initialize points of the mouse direction
Vec3 p0, p1;

// get the current player (camera)
Player player = Game.get().getPlayer();
if (player == null)
	return 0;
// get width and height of the current application window
int width = App.get().getWidth();
int height = App.get().getHeight();
// get the current X and Y coordinates of the mouse pointer
int mouse_x = App.get().getMouseX();
int mouse_y = App.get().getMouseY();
// get the mouse direction from the player's position (p0) to the mouse cursor pointer (p1)
player.getDirectionFromScreen(out p0, out p1, mouse_x, mouse_y, width, height);

// create an instance of the GameIntersection class
GameIntersection intersection = new GameIntersection();

// try to get the intersection with an obstacle
// cylinder has radius 1.5f, intersection mask equals to 1
Obstacle obstacle = Game.get().getIntersection(p0, p1, 1.5f, 1, intersection);

// check, if the intersection of mouse direction with any obstacle was occurred;
if (obstacle != null)
{
	// show the coordinates of the intersection in console 
	Log.message("The intersection with the obstacle was here: ({0} {1} {2})\n", intersection.getPoint().x, intersection.getPoint().y, intersection.getPoint().z);
}
