Can I detect a building upgrade through Lua?

[KINGTUT10101]

Hello,
I am wondering if you can detect building upgrades through Lua. I know you can detect certain buildings through Draft.getDraft (""), but I would like to know if this would work with upgrades, or if there's another equivalent.

I never try that, but there are some functions to detect building upgrades.

Code: Select all

function script:event(x,y,level,event)
if event == Script.EVENT_UPGRADE ...
-- and
Tile.hasBuildingUpgrade(upgradeId,x,y)

How would I know the location of the building though? It seems like you'd have to know that for this to work. Also, I need to check this for these upgrades on every frame.

Im not sure but try this

Code: Select all

local draft = Draft.getDraft("Draft")

function script:event(x,y,level,event)
 if event == Script.EVENT_UPGRADE and Tile.getBuildingDraft(x,y) == draft and Tile.hasBuildingUpgrade(x,y) then
 
 -- other stuff
 
 end

The x y values in script:event(x, y, level, event) would be the location of the building.

So I don't need to provide values for them?

Yes, I wrote something about functions if you want to take a look: viewtopic.php?p=161342#p161342
