I'm trying to remember the English name for a memory model of a map built exclusively for handling collision detection. I think this is especially frequent in tile-based platform games.

I believe the Spanish term for it is "Mapa de durezas".

If you have a Super Mario tilemap like this:

    C     +        'P' = Pipe
         +++       '+' = Brick
        +++++      '@' = Ground
   P   +++++++     'C' = Cloud
 @@@@@@@@@@@@@@@@  ' ' = Air

Then the <ENGLISH EXPRESSION THAT I'M LOOKING FOR> of that map would be:

          *       '*' = Solid
         ***      ' ' = Traversable
        *****     
   *   *******
 ****************

Any clues?

The term you are looking for may be "collision map".
