tags: debug title: Physics debug brief: This example allows you to toggle physics debug visualization as well as changing the time step so the simulation runs at one tenth of the speed. author: Defold Foundation scripts: physics.script, loader.script

With the physics visualization on, all collision object shapes are visible. In addition, at intersections the normals at the collision points are shown.

The example collection consists of:

• 4 blocks with dynamic collision objects with Restituion 1.0, so they bounce forever,
• 4 walls with static collision objects forming boundaries for the blocks,
• game object go with:
  • label with example description,
  • a script physics.script included below.

This collection is additionally loaded via a Collection Proxy component in main.collection. Therefore, sending message set_time_step to its url "main:/loader#physicsproxy" is causing the proxy to have a different update time, causing e.g. the slow-motion effect, which might be helpful when debugging physics.
