collision_to()

Variable * collision_to	(	Environment *	_environment,
		int	_sprite )

Emit ASM code for = COLLISION([int]x).

Parameters

_environment	Current calling environment
_sprite	Integer with the bitmask of the sprites

Returns

Variable* Temporary variable with the result of collision (0 = no collision, 1 = collision occurred)

Parameters

_environment	Current calling environment
_sprite	Expression with the bitmask of the sprites

Returns
