- Yes, please do so.

- Yes, the problems are many. But for the memory, one would need, say, 2 bits
- as on the map there are a few colors for the walls. But we don't need the
- full resolution (anyway, we only have a small screen to display it) as the
- coordinates used by doom are very precise: one unit is one texture pixel.
- This answers your question about the positions of objects, too. There's no
- need to have fixed point coordinates: the integer coordinates give smooth
- enough movement. For the collisions with objects, each object has a "radius"
- which is specified in the wad.
- Back to the map. If we have a resolution of two or four length units, it
- divides the space the map takes by four or sixteen, giving 256ko or 64ko.

- Some mechanisms are triggered by crossing lines, if I remember correctly.
- The details are in the specs. I'll browse it once more and tell you tomorrow.

- The positions and radii are known.
