SPRITEORIENT

Description

This BASIC command will change the orientation of a Sprite.

The four possible directions are: normal (this is the default orientation), flip, mirror, and rotate180.

The Background and Sprites will not show up until a DRAWSPRITES command is issued.

Syntax

Possible syntax using mirror orientation as an example.

1. Print #main, "SPRITEORIENT spritename mirror"
2. #main, "SPRITEORIENT spritename mirror"
3. #main "SPRITEORIENT spritename mirror"

Hints

Lets suppose you want to have your playable character facing to the right direction when he goes into that direction but the bitmap of such sprite is looking to the left. Then use mirror to make the sprite face the other way around.
