Hi,
I've noticed that the simple shadow script in the templates is impossible for me to recreate, because the shadow sprite must c_trace downwards to the ground an stay under the object, but when it traces it produces a you pointer to whatever it hit, and that "you" will replace the original thing that it's supposed to stay under. Now I've heard that you can use arrays to solve this, but the thing is I havn't used arrays yet and can't see how you could use them to keep track of the original object.
