Blender uses a visual click-and-drag system to create basic game
interactions.
• Sensors; A sensor will detect some form of input. This input could be
anything from a key press, a joystick button or a timer that triggers every
single screen update (or frame) of the game.
• Controllers; Controllers are used to link Sensors to Actuators. They
allow for some more complex control over how sensor and actuators
interact with each other.
• Actuators; An actuator will actually carry out an action within the
game. This can include moving an object within a scene, playing an
animation, or playing a sound effect.

2.5.2 Sensors, controllers and actuators logic bricks
Game Blender has 28 different sensors, controllers and actuators. All these
logic bricks make it possible for objects to start “thinking” for their own.

2.6 Physics within Blender
A physics engine is a computer program that simulates Newtonian physics models,
using variables such as mass, velocity, friction and wind resistance. It can simulate
and predict effects under different conditions that would approximate what happens
in real life or in a virtual world.
2.6.1 Particles
To create particles, you will first have to enter the Object menu (F7) or press
the icon with the three-way arrows (the one in a row of 6 icons), which is
