Game crash from damage indicator UI in some cases #4909

Open Cervator opened 3 years ago

Cervator commented 3 years ago

What you were trying to do

Test MetalRenegades. Fix is likely needed in the Health module, but maybe hardening against unexpected UI state is something we can help in the engine? If just a quick fix in Health then this is probably a small easy bug to handle.

What actually happened

Local RL baby helped me detect a bug by taking my attention away. Game had main menu up but it was night time and there were MawGooeys around. Came back to a crash I figured happened because one of them hit my character while the main menu was up thus some UI stuff wasn't in the right state to receive a damage effect. Mentally increased the baby's kill score.

How to reproduce

Log details and game version

I need to investigate the NullPointerException more to figure out whether the implementation is missing a check there (https://github.com/MovingBlocks/Terasology/issues/4909#issuecomment-922374801).

The ClassCastException issue (https://github.com/MovingBlocks/Terasology/issues/4909#issuecomment-922376970) seems to be an issue of renaming? 🤔 I need to check whether I forgot to change a reference, or whether that is an issue from loading a game state with (active?) damage overlay from an older version...
