Some questions

1. how can i make an item cost like 800 and when you sell it you get more, say 900, 1000 something like that. Or do it always take half when selling it?

2. How can I remove the grass and pathing thing under buildings? Its annoying, destroys my city..

3. How can I make buttons inside buildings and units that starts a trigger?

1. I don't know about this, but try Game Constants; there might be an item sell cost factor or something.

2. Are you talking about the building's Ground Texture? If so, just set it to none in the unit editor, and it's gone.

3. Buttons inside of buildings and units? You mean when you select the unit a button shows up in the control card? If so, give the unit an ability that does nothing, then set a trigger to catch the order string for that ability, and you're in business.

good luck

Thanks, Now I only miss the buy thing. I want to buy drugs, and sell it at high price, in warcraft game ofcourse..

I really need this? Nobody?

Well, i have an idea, but i dont know how to simply "increase" the amount an item sells for on the item itself, but maybe if you make a trigger, for example:

Events
Unit- A unit owned by Player 1 (RED) Pawns an item (to shop)
Condition
(Item-type of (sold item)) Equal to Tome of Experiance
Action
Player- Add 500 to Player 1 (Red) Current Gold


That trigger should add an extra 500 gold (or desired gold amount) + the amount that the item sold for, so if an item at a shop costs 1000, but sold for 500, and you wanted it to be 1200 for it to be sold for, you would set the gold amount to 700. You would have to make a few triggers which would take up some bits.
