4 hours, zoned in for most of it, spent some time at dollar town today too.
Created a layer structures that is going to allow me to keep track of my object types. Player 1 ignores collision with black tiles, moves at the approximately correct speed of 10 tiles per second, a speed that will remain constant even if the tile sizes change from map to map. Players can now shoot projectiles that are 20% a tile's size and move in the direction of the arrowkey pressed. When two or more firing keys are pressed simultaneously the priority of which button prompt is followed goes left, right, up, down. Projectiles seem to move at about 11 tiles per second but I'm not 100 on that. There is no delay between shots fired in the same direction, but shots fired in different directions have a delay between them. That delay period is not perfect yet, but close at about 1/5 a second. Projectiles ignore collision with black and white tiles, but care deeply about inactive tiles, other bullets and enemy players. These specific object types cause the projectile to delete, further interaction forthcoming. Ammo is currently limited to 5, but the regeneration system will be built tomorrow. Neato, its coming together smoothly so far.
