Description

Scrolls the map in the direction specified.

Parameters

map - Map pointer returned by the NEWMAP function.

direction - A directional constant.

Remarks

This command updates the internal position of the map by scrolling in the direction specified by the distance specified.

The direction argument can be one of:

@SCROLLUP

@SCROLLDOWN

@SCROLLLEFT

If the tile data was created with scroll wrapping set to TRUE then the map will continuously scroll in the direction specified with each call to SCROLLMAP. The map must still be rendered with DRAWMAP to show the changes made while scrolling. The amount argument is a positive integer.
