A simple 3D 100-line free-look camera for Godot 4.0 that mimics the functionality of the editor's camera for in-game use.
Ported from Adamviola's Godot 3.2 version.
Use W and S to move forward and backward.
Use A and D to move left and right.
Use Q and E to move up and down.
Roll the scroll wheel to increase and decrease movement speed.
Press shift to move faster, and hold alt to move slower.
Hold down the right mouse button to rotate the camera. There's a slider in the editor to control mouse sensitivity.
Attach camera.gd to your Camera3D node. That's it!
