A couple of people asked about the wobbly trees in ECO WARRIORS, so we're sharing this (super simple) trick!

The bullets and explosions apply a force to the trees (and other objects). To the right of these gifs you can see the values of the configurable joints that secure the trees to the ground.

The trees have a mass of exactly one unit and are about four units high with the anchor of the joint exactly on the ground in these simulations. As you can see, with such a tall object a really high angular drive is needed to pull the object upright after a knock.

Try this out in your next LD Jam!
