As it says on the tin, a new research_trigger type that only activates when a building has been damaged and needs repairing, and/or when an entity has been destroyed would be a nice addition and would allow for a lot more customization in mods in regards to trigger technologies.
The main example (and the main reason why I made this request) is for repair packs, having them unlock when an entity gets damaged sounds a lot better to me personally; another example that mods could implement is having a specific technology unlock when a player kills a biter, or other enemy.

I hope this sounds useful enough to implement in some capacity, and thank you for reading :]

I have nothing against the request itself, but the idea of locking repair packs behind entity being damaged is just silly. That's when you want to already have them.

thats fair enough tbh, the idea made sense in my head when first thinking about it, but time does what time is - but as you said, having some capacity of this would be super neat
