''A note on the current sprite'': when the current sprite index ''I'' is set (that is, greater or equal zero), all functions that act on sprites by pointer ('''S''') are also available since the sprite pointer is set to point to the ''sprite[]'' array at index ''I'' in this case. The converse is not true, however: the sprite pointer could be set to a sprite structure other than the main ''sprite[]'' array (such as the ''tsprite[]'' array of sprites drawn on the screen), so code in a scope where the sprite pointer has been set ('''s''') cannot use functions accessing the ''sprite[]'' array ('''I'''). | |||

Revision as of 09:45, 4 August 2010
This is a categorized list of every command in Mapster32-script.
Legend:
I: acts on current sprite, S: acts on current sprite by pointer (also valid in "for i drawnsprites")
i: sets current sprite, s: only sets current sprite by pointer
D: differs from CON, X: deprecated/do not use (yet)
var/array/special: must be writable, [something]: optional command field
A note on the current sprite: when the current sprite index I is set (that is, greater or equal zero), all functions that act on sprites by pointer (S) are also available since the sprite pointer is set to point to the sprite[] array at index I in this case. The converse is not true, however: the sprite pointer could be set to a sprite structure other than the main sprite[] array (such as the tsprite[] array of sprites drawn on the screen), so code in a scope where the sprite pointer has been set (s) cannot use functions accessing the sprite[] array (I).
