Sprite_getDefaultMass()

double Sprite_getDefaultMass

(

CmdFX_Sprite *

sprite

)

Gets the default mass of a sprite.

The default mass of a sprite is calculated by the number of non-whitespace characters in a sprite map. ANSI codes have no effect on the mass of a sprite.

Parameters

sprite

The sprite to use.

Returns

The default mass of the sprite.

Sprite_getMass()

double Sprite_getMass

(

CmdFX_Sprite *

sprite

)

Gets the mass of a sprite.

This will default to Sprite_getDefaultMass if a custom mass has not been set.

Parameters

sprite

The sprite to use.

Returns

The mass of the sprite.

Sprite_resetMass()

int Sprite_resetMass

(

CmdFX_Sprite *

sprite

)

Resets the mass of a sprite.

This method will reset the mass of a sprite to the default value.

Parameters

sprite

The sprite to use.

Returns

0 if successful, -1 if an error occurred.

Sprite_setMass()

int Sprite_setMass	(	CmdFX_Sprite *	sprite,
		double	mass )

Sets the mass of a sprite.

This method can be used to set custom mass values for a sprite. You can still calculate the original value with Sprite_getDefaultMass.

Parameters

sprite	The sprite to use.
mass	The mass of the sprite.

Returns

The mass of the sprite.
