Hi,
(1) camera that follows player can be done this way :
assume variable player is the pointer to the player entity ...
... if you move the code in the players action you can replace "player" by "my"
#define CAM_DISTANCE 200 // distance to player
VECTOR v; // helper variable for vector
vec_set(camera.x,player.x); // camera on players position
vec_set(camera.pan,player.pan); // look same direction as player
vec_for_angle(v, camera.pan); // get the vector for the direction
vec_normalize(v,CAM_DISTANCE); // set lenght of vector to distance of camera to player
vec_sub(camera.x,v); // subtract vector from camera position (= move backwards)

Have a look into the online manual section Precompiler->#define; PRAGMA_PATH is explained there.
You can also use add_folder(). (necessary if you want to have a directory structure also in the published game)
