Issue Report

During nest missions, players can interact with Mudraptor Eggs. This will show the inventory of the egg for a brief moment before the inventory closes and the player grabs the egg. If the player drops the egg, it will float where it was last dropped. Finally, if the player takes all of the eggs out of the cave, the nest objective will be considered complete. We didn't even make it out of the cave before the objective cleared.

Reproduction steps

1. Start a campaign save (or mission mode; I haven't tested this however) and pick a nest mission
2. Make sure the nest is a Mudraptor nest
3. Enter the nest and left click the Mudraptor Egg
4. Observe how you can pick it up
5. Move away from the wall or floor and drop the egg
6. Observe how it doesn't move and floats where you left it
7. Pick the egg back up and start leaving the cave
8. Observe how (if all other eggs are stolen or destroyed) this completes the mission objective

Note: egg densities were adjusted in the item density pass. So if these need further adjustments, do it there.

Egg stealing is unexpected but interesting. Me and my friends had fun taking eggs from abandoned outposts for deconstruction or fabricating petraptor eggs. Is there any chance of keeping it as a feature?

[Regalis11]

I agree that stealing them (and selling them for profit, deconstructing them or turning them into pet raptor eggs) is an interesting unintentional side-effect that we should probably keep. But we need to take that into account in the nest mission logic, which disables their physics when attaching them to the cave.

[Regalis11]

Actually it seems the issue wasn't how the physics are disabled: this had already been taken into account by reactivating the physics when the item is picked up. The problem was the eggs were using the default (neutrally buoyant) density, which seems to have been addressed as a part of an item density fix pass that we did recently (not included in any public build yet).

[Regalis11]

Actually we decided to make the large eggs non-pickable again: being able to loot them caused too many problems, messing up the reward balance of the missions and allowing exploits by doing an abandoned outpost mission and repeatedly looting the eggs. https://github.com/Regalis11/Barotrauma-development/commit/ed6d9800f0dbca432fdec347163f606fe90dfbd7

Tested, working correctly. Closing.
