Is there any known issue with cc.Collider Cocos Creator at v1.4.0? I’m facing an issue where diff node hierarchy sequence affects whether the collision is detected or not. Try it yourself when you swap the sequence of player and enemy node in the editor node tree.
So I chased the rabbit and found the cause of the problem. The group manager in the 1.4 editor is making errors at setting the collision matrix config. There’s a simple workaround this by setting the collision matrix yourself. The config is placed at ‘ProjectPath/settings/project.json’.
