Generating lots of scripted NPCs using generate entity lags the game. Also, Dischorran's troll contest entry caused DROD to crash for me, which doesn't seem entirely unintentional on his part.

Now, here's the trick: this happens even if you use the End or Imperative Die commands. Active NPCs devouring the memory isn't something anyone can really fix. I don't know the fancy inner workings of how undo works, so it might be impossible to clean up Ended NPCs. But if it isn't, Generate Entity is kind of a memory leak.

I think that's prone to happen as long the game's instantiating and destroying objects (note the Unity-esque terminologies, because they hit upon this very oftenly) per step.

The common solution to this problem is to use pooling, but that probably requires a massive change to the DROD engine. Or we may try to do that in our scripting, but this is not always possible.

I think we already talked about this before in the chat so maybe I am simply repeating myself, but there aren't any game-scope memory leaks in the game. The NPCs are not prunned from the memory until you leave the room, but you need to create millions of NPCs for,it to have any conceivable impact. Just see how much that entry has to abuse things for problems to start happening.

For me it's a problem in theory, not in practice.

Edit: Four years later I stand corrected.. Marking as "not a bug" because it's a duplicate.
