Create collisions part of PlayerController script - tilemap Overworld

Part 3
1 problem: can't add the SolidObjects layer in the inspector. @randomrok can you figure this out? We need to add the SolidObjects [regular] layer as a parameter/value for a variable in the script (through the inspector) to prevent the player from walking into things based on the Overworld Tilemap
