type
This string identifies the avatar and must be passed to the OpenSpace.createMyAvatar method.
className
Linkage class name of the avatar movieclip in the Flash library of the reference passed to the OpenSpace.initialize method.
animTime
The time (in milliseconds) it takes to the avatar to move from one tile to the next one along diagonal directions (a correction is applied for the vertical and horizontal directions); in other words this is the speed of the avatar.
stature
The height of the avatar, used to check if the avatar can walk under over-passes like in this example:
cp0, cp1, cp2, cp3 (control points)
These four control points "describe" the avatar projection on the ground, like in the following picture:
OpenSpace makes use of the control points to check the avatar position with respect to the tile, to decide whether the avatar has reached the next tile during movement or not. They are also used when the "pixel perfect collision" is used, to calculate avatars and surrounding objects overlapping (not recommended, to avoid performance issues).
Setting the control points is optional: in case you do not set them, the avatar (0,0) coordinate (which should be located between the avatar's feet; the + in the picture above) is used by the OpenSpace engine. This is usually enough to have an excellent avatar behavior.
Please notice that if you use the control points, they can't exceed the tile size.
