Detailed Description

Updates animation state of Animated Color Sprites.

Function Documentation

sm2_init_sprite()

void sm2_init_sprite	(	sm2_Sprite *	s,
		const sm2_SpriteSheet *	sheet,
		const sm2_FrameTag *	tag )

MSX2 Construction and (re)initialization of the animated color sprite.

Parameters

s	Sprite object to be (re-)initialized.
sheet	Sprite-sheet object.
tag	Frame-tag object that defines the range of animation frames.

Note

This function can be used not only for initialization but also for switching the animation pattern (sprite sheet and/or tag) of a sprite object.

sm2_update_sprite()

void sm2_update_sprite

(

sm2_Sprite *

s

)

MSX2 Update the animation state of sprite object.

Parameters

s	Sprite object.

Note

In order to update the animation state of the sprite object, sm2_update_sprite() and sm2_update_sprites() should be called periodically (as much as possible at each VSYNC timing).

Both sm2_update_sprite() and sm2_update_sprites() can be called from the VSYNC interrupt handler.

sm2_update_sprites()

void sm2_update_sprites ( sm2_Sprite ss[], size_t num )

inline

MSX2 Update the animation state of a series of sprite objects.

Parameters

ss	An array of sprite objects.
num	Number of elements of the array.

Note

In order to update the animation state of the sprite object, sm2_update_sprite() and sm2_update_sprites() should be called periodically (as much as possible at each VSYNC timing).

Both sm2_update_sprite() and sm2_update_sprites() can be called from the VSYNC interrupt handler.
