Map Editor Questions

Blitz3D Forums/Blitz3D Beginners Area/Map Editor Questions

Few more general questions:

a) Rather than use arrays to store tiles and maps, I was thinking of using Types for botht he tiles and the map data, allowing me to combine information. Is this more efficent/faster than using arrays? Or am I better off with separate collison maps/tiles?

b) I wish to implement a Zoom function, allowing the user to Zoom out from their map (probably -2x, -4x, and -8x) - is there a graceful way of doing this?
