* Basic Mob Carp Part II: Regenerator (#71437) ## About The Pull Request <details> <summary>Video</summary> https://user-images.githubusercontent.com/7483112/203324325-5bf46e0f-b294-4832-9016-aec275036ca9.mp4 </details> Adds a "Regenerator" component, applies it to carp, and removes the previous implementation from megacarp. The function of this component is that any time you take damage a timer is reset, when that timer expires you will begin regenerating health and display an animated border for visual feedback. This was previously a function of mega carp but was extremely obscure because there was _no_ feedback, so it would only be visible that it was happening if you were wearing a medical hud. Additionally because mega carp will pursue a target until it dies you probably wouldn't notice it even then, it had to survive a fight in order to gain any value from this. This will still be true for all carp until AI changes are pushed, so until then this isn't going to do very much for NPCs but might be a small buff to player controlled carp (though those can all retreat to a carp rift for a similar effect). This also modifies a few "defence" procs which were either directly setting HP or neglecting to call signals from a base proc, as they would bypass triggering the effect. This should make them more reliable for other things which rely on those signals too. ## Why It's Good For The Game Gives an iconic creature some more unique behaviour than "moves directly towards you and bites". Gives visual feedback to some behaviour which has existed invisibly for a long time. ## Changelog 🆑 add: All Space Carp will now start regenerating health after 6 seconds of not taking any damage, until they're back to full health. This behaviour was previously unique to mega carp. /🆑 * Basic Mob Carp Part II: Regenerator Co-authored-by: Jacquerel <hnevard@gmail.com>
