Vehicle Collision Box

My Car Model
  •  2706 polygons
  • When your car collides with another object, the force of the collision is calculated for each polygon.
  • A lot of polygons means a lot of calculations.
  • Which hurts the frame rate of your game.
My Collision Box 
  • 68 polygons
  • A collision box is a simple model of your car. 
  • Fewer polygons means fewer calculations are needed for each collision. 
  • Which means a faster framerate for your game.
Replace Mesh Actuator  
  • This tutorial uses the Replace Mesh Actuator to replace the Collision Box mesh with the Race Car mesh. 
  • It does not replace the Collision Bounds.
