Hi Lin, firstly, I'd like to thank you for making this editor. I've always wanted to edit OOA/OOS and now I can, thank you.
Secondly, I have a question to ask.
Where are the maps for indoor houses? I cannot seem to find them at all... and what is with the yellow boxes in the unmapped areas?
EDIT: How does one add sprites such as NPC's? Also, how does one make a warp work exactly? I want to be able to make Link enter those cave entrance tiles and enter the cave...
Maps for the indoor houses are normally found in the extra space in the underwater present or past. Look towards the right side and the bottom of the Map after selecting "Underwater Present" or "Underwater Past." As to NPC's, the only knowledge I have on those is that they are events called "common regular events." If you want a particular NPC to appear, find him/her and copy the ID from his/her event. I do not know how to change an NPC's appearance. Warps are tricky but simple once mastered. They are similar to editing a treasure in the way that you must find one from a different map and swap it to your map. The only categories you need to mess with are: Dest. Group (the map group where the warp leads. Present Overworld = 0, Past Overworld = 1, etc.), the Map category (the map in which you step into the warp) and then Destination Map and Position. Destination Map and Position are both located in the "Follow and edit warp" button. The Destination Map is the map that the warp will lead you to, ie 3A when you exit the house where the Harp of Ages is found. The Position is the coordinates on the map where the warp will place you.
Simple question:
How can I change the map a chest uses?
I can't find a "Map" field in the chest editor, so I'm pretty confused.
The "Map" You're looking for, is a map that contains a treasure. Look for a map that has a treasure on it, MAKE SURE IT IS IN THE SAME MAP GROUP (present overworld, past overworld, etc.) and look at the ID of the map. For example, the treasure you pass on your way to go visit Nayru for the first time is located in map "49". When you're using the chest editor, have the engine search for map 49 and swap map data, then align your Y/X values with the treasure tile you have placed on the map. The ID is what happens when the treasure is opened. Lin has posted a weapons list to acheive certain weapons from a chest and a chest fixer program to help prevent glitching.
Do Not take my word for it, but I believe Lin is working on a tutorial for both the warps and the treasures.
