Calcualtes a bounding box using all the nodes in the scene and sets it as the allowed area for the camera This method is currently called whenever a node has finally been set in place. And when a missions was just loaded. There should be a way to avoid recalculating the bounding box each placement, but due to time constraints I couldnt do it.

This method will clamp the given position to the grid if the SnapToGrid setting is true. Otherwise retunrs the same position

Parameters

position

The position that is required to be clamped by the SnapToGrid function if able

Returns

A position adjusted if SnapToGrid is set to true, otherwise the same that was given.

This method will check if any of the zoom buttons in the UI has to be disabled (if a value is maxed out)

This is the Fit-In-View method. Will make all the nodes of the mission fit inside the camera frustrum
