Description

All of the functions above will return an array (which can be empty) of buildings. 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).

Example

-- destroy all buildings in the circle!
buildings = harvest.findBuildings(x, y, 200)
for i=1,#buildings do
   local x,y = buildings[i]:getPosition()
   harvest.spawnParticle(buildings[i]:getDeathParticle(), x, y)
   buildings[i]:remove()
end
