The buildings will be of user data lua type, and refer to a CBuildingLuaInfo in Harvest's C++ code. On these objects you can perform getPosition(), getId() and various other functions (see separate thread soon). However, you may not keep a reference to these objects since it's not possible to predict when a building is destroyed. Instead, if you need to keep track of a specific building, you will have to save it's ID number and then locate it each frame with harvest.getBuilding(id).<br /> <br /> === Example ===<br /> &lt;pre&gt;<br /> -- destroy all buildings in the circle!<br /> buildings = harvest.findBuildings(x, y, 200)<br /> for i=1,#buildings do<br /> local x,y = buildings[i]:getPosition()<br /> harvest.spawnParticle(buildings[i]:getDeathParticle(), x, y)<br /> buildings[i]:remove()<br /> end<br /> &lt;/pre&gt;<br /> <br /> === Resources ===<br /> *[http://www.oxeyegames.com/forum/viewtopic.php?p=1523#p1523 Oxeye Game Studio Forum - Harvest Functions]</div>
