( any -- bool ) True if the value is a class, or false if it is any other type. Error if it is a sound. chain ( any -- bool ) If given an object of the same class as the current object, selects that object as the current object and continues executing the code with that object instead. This new current object is not saved if you return from a function or a subroutine call. If it successfully chained, then the result is false. If given an object of a different class, an object that doesn't exist, or anything other than an object, then it does nothing and the result is true. Create ( class x y image dir -- obj ) ** Creates a new object at the specified location, and returns it. The result is zero if the class is zero, the coordinates are out of range, the object cannot be created due to the CollisionLayers, or if the new object is destroyed before its CREATE message returns. cz? ( any -- bool ) |
