Units that sell items.

I know this is possible as i have seen it in several AoS maps, units and heros can be made into item sellers, i have tryed various things but i cant seem to get it to work, thanks for any help you can give me.

give a building a unit model.

I think it involves SLK editing, as I'm pretty sure each unit's section includes all the fields shown in the unit editor (such as the ones like Items Sold which are not visible if you're editing a unit). Once you've got that far, I can't help you.

This is easy

Just take a merchant unit, change the model and icon to the unit you want it to look like.
Then set the pathing tile (The ground arround buildings) to either something smaller, or nothing.
Change the sound to the unit sound.
REMEMBER to change the selection scale, or your merchant will have a large selection circle arround it, looks stupid.

And boom, u got a unit that sells items

As simple as that

You can also download an enhanced editor like UMSWE or WE Unlimited which gives all units the ability to sell items.

Also, you can put this UnitMetaData.slk file into your Warcraft III\Units\ directory. You don't need to insert it into your map. It's the file that tells the WE what fields to enable for units in the Unit Editor.
This one I've altered to enable the "Units Sold" and "Items Sold".

thanks panto, thats what i was looking for, i actually wanted UNITS to sell items so i could move them around ect, i didnt want a building that sells items that looks like a unit.

I hav a question here..

When i try to sell things to them Shop ( a unit )

But after i right click the item n point on the unit n left click to sell
It didnt sell but the item juz drop near the unit

Can anybody teach me how to sell the item on the unit ?

You have to put the ability on the unit which corresponds to being able to buy items back from the player. I don't remember what it's called.
Looking at an existing shop should give you your answer.

No no no you just change the model file of the shop and select the walkable button its easy.

use the unitmetadata.slk its the easiest way, and for units/buildings to buy items, you have to give them the buy item abil
