This iExpression is a variant of the 'Throw 2D' iExpression in which the thrown object cannot only bounce of the ground but also bounce of some walls. There are two different walls available. Besides the position of the walls you can also specify how elastic the thrown object bounces of the walls. In case you need just one wall, you can simply choose for both walls the same position.

  • Ground Height

    determines the height of the ground level at which the object bounces. This value should not be animated.

  • Elastic Bounce Ground (%)

    determines how elastic the object bounces from the ground. 100% means that the object behaves like a bouncing ball, 0% means that it does not bounce at all.

  • Walls
    Wall 1 Position

    is the (x) position of the first wall at which the thrown object may bounce. This value should not be animated.

    Wall 2 Position

    is the (x) position of the second wall at which the thrown object may bounce. This value should not be animated.

    Elastic Bounce Walls (%)

    determines how elastic the object bounces from the walls. 100% means that the object behaves like a bouncing ball, 0% means that it does not bounce at all, but slides downwards along the wall.

  • Physics
    Gravity

    determines how fast the thrown object falls down i.e how strongly it is attracted by gravity.

    Air Resistance

    determines how much the object slows down (in horizontal direction) while it is in the air.

    Friction on Ground

    determines how much the object slows down (in horizontal direction) while it is sliding on the ground.

  • Simulation Start
    Start at

    controls at which point in time the simulation starte (at the last keyframe, an a manually chosen keyframe or at a manually chosen frame)

    (Key) Frame No.

    is the frame or the keyframe (depending on the choice of "Start at" option) at which the throw simulation starts. When "Start at" has the value 'last keyframe' this option is ignored.
