Some kind of function for an item script...uhh forget it. Just read. ;p

[Gleeok]

Alright here's my problem and the set up:


Upon use the item script fires an ffc and changes the the ffc->Data. When the data on the ffc script is changed a new statement opens up. Sounds familiar right? Yeah that part works fine. Here's where my scripting knowledge ends:

When the Item is used a second time it opens up a portal and ...oops teleporter* (+2 points to name that reference.) BUT If Link were to teleport just anywhere he wanted to on screen that would be bad. So I need to add on to the Item script that can call from a global function (like if ffc->X && ffc->Y is_walkable for example) so to not permit a teleport if the called ffc is over a non-walkable combo. But I still need it to be able to pass through non-walkable combos.

Unfortunately I have no luck with these.:( Most likely because I don't really understand them. Any help much appreciated.

Sounds like you're looking for Screen->ComboS[ComboAt(ffc->X, ffc->Y)]. That'll give you a four-bit number representing the solidity of the combo at that location. It'll be 0 if the combo is entirely walkable.

Yes, that's the one! I was trying canMove and some variants of is_walkable which quite frankly, sucked balls when used for this particular script.
