Today we combine two very powerful iExpressions: We use the ‚Throw 2D‘ to bounce a layer off the ground and against some walls and the ‚Elastic Shape‘ to deform it accordingly. Since everything is based on expressions, you can simply set a different throw direction and all the phyics and deformation update instantly. Create bouncing animations fast and effectively – and thanks to iExpressions without the need to write any expressions code yourself.
