6 months ago Hi, I am the original issuer of this request. Could you maybe change the description + title to:
Title: [Function Request] physics_joint_exists(joint)
Feature Type: feat_addition_ingame return: boolean param: joint desc: Check if the joint does still exist in the game.
Benefit: The problem at the moment is, that joints get automatically destroyed by the engine if one of the 2 connected instances gets destroyed. In this case accessing the none existing joint will SILENTLY CRASH the game.
Therefore we need this function.

Feature Type: feat_addition_ingame Description: function name: physics_joint_exists(joint); return: boolean param: joint desc: checks if the joint does still exist
Benefit: The only problem at the moment is, that joints get automatically destroyed if one of the 2 connected instances gets destroyed. If both instances have a reference to the joint, then I sometimes face bugs like that. Even If i really try to detect all instance_destroys to tell the other connected instance, that this joint isnt existing anymore. I need the joint references to detect to high forces, so the joint gets deleted and the boat breaks.
Here a video, so you can see, that it can become difficulty to mange this workaround: Its in the additional info URL
Example Google Play crashlog if I miss one joint reference:
