Today (07/18/24) we started to learn about how to create a 3D game/model on Godot Game Engine. We began with creating the ground.
We started off by using a 3D Node, after that we added a MeshInstance3D to create the ground. To increase it's size we changed both the y and z coordinates to 100 m. We then added a CollisionShape3D. However, it's size wasn't the same as our land-mesh; to fix that we changed it's size (by changed the y and z coordinates) so it could be the same as the land-mesh. After we fixed the collision-shape, we added a StaticBody3D.
There was an error for both the StaticBody3D and CollisionShape3D. To fix those error we had to move the CollisionShape3D below the Static-body, making the Collision Shape it's child and also getting rid of said errors.
