Objective: to be more informed on blender’s game logic sensor function.
Materials: Blender, game logic editor, actuator
Method: turn an object react if its near others. Under the sensor option, try the near option and connect it through the control and actuator. Make sure the actuator is set to invisibility and un-check the visible box. turn on the rigid body and make it fall on another object.
Result: It should vanish when its near the other object and re-appear falling when it gets away from it.
Discussion: its straight forward. next try doing the same thing but with the collision sensor. It should be the same outcome. try different option and see what happens.
