hey, thanks for checking out the game! With the tree resource room, one of the spawned trees will always contain a key. Could you have missed a tree? I'll look into this more though, thanks for letting me know
I believe I figured out the issue. The player collision box is slightly too large so you technically clip into the door when too close to it, so your raycast is pointing at 'nothing'.
In an upcoming fix, I will revise player collisions and add text UI helpers to let the player know when they're able to press E to interact with doors, resources, etc.
