Backdrop

A backdrop in TGF and MMF represents the background and foreground within a project. These backdrops can be set to interact with various objects to act as an obstacle, platform, and even a ladder. Quick Backdrops tile quickly, hence the name. Regular backdrops do not. Changing the size of a regular backdrop just stretches the image so if you choose to use them you'll have to place one backdrop at a time or use the duplicate function in MMF. Backdrops are behind all other objects and can only be located above "active background objects".

In TGF2/MMF2, backdrop objects can be placed in front of active objects and the like, if the layer they are on is above said objects' layer. Currently, cross-layer collisions are not supported, nor are collisions with hidden layers.

Backdrops should be used whenever possible, as they are not subjected to object count limits. Due to their lack of values, flags, and action/event sets, they use much less memory than active objects, and large backdrops have no effect on the game's speed.
