Regression

No

2D Colliders will not update their collision shapes when changing Transform Scale from zero on runtime

Physics2D

-

How to reproduce:
1. Download and open the attached project "case_1164935-matchtree.zip"
2. Select the Cube GameObject in the Hierarchy and inspect the Collider components
3. Start Play mode
4. Inspect the Cube GameObject's Collider components

Expected result: Colliders update their collision shapes
Actual result: Colliders do not update their collision shapes and throw a warning

Reproducible with: 2017.4.29f1, 2018.4.3f1, 2019.1.9f1, 2019.2.0b8, 2019.3.0a8

Notes:
Only BoxCollider2D and CapsuleCollider2D are affected by the issue.

  1. Resolution Note (fix version 2019.3):

    The issue was caused by SyncTransforms not being run prior to the simulation being run. This was caused because no valid shapes existed in the world resulting in an early-out of the simulation step therefore avoiding the SyncTransforms call. Whilst the world wasn't empty (there were 2D colliders), there were not shapes which is what the empty-world test does. The fix is to correctly run SyncTransforms during the simulation step.
