I don’t understand why it’s causing such severe lag.

There’s an issue during the process where the player departs from the spaceship and descends to the planet’s surface. When the player departs and the cargo pod begins to descend, the framerate drops sharply and the game stops progressing.

end)

The details related to this issue are as follows:

1. If create_building() is not called, the planet’s surface is completely covered with lava, leaving no space for the player to walk on.
2. In the early stages of development, there were no problems when attempting to land directly on the lava.
3. Even if I force the chunks to generate beforehand, as done at the beginning of the create_building() function, the same problem still occurs.

I can’t find a convincing reason why this issue happens. Has anyone experienced a similar problem?

Without the "create_building" you've limited the map size to a small area - which likely has no landable space for the cargo pod and so it gets stuck trying to find a place for the cargo pod on a surface that will never have one.

[Xeon257]

That’s correct. However, in the early stages of development, when I attempted to land on the lava, the landing was successful, and the player was placed in a state where they couldn’t move on the lava.

Could it be that the forced landing being successful was actually a Error?
