Mined Area Widget
Posted: 19 Dec 2008, 08:59
This is a super-simple Widget, for a super-simple purpose. For whatever reason, Spring 0.77b5 doesn't render the metalmap's "mined" status very clearly on my hardware (devs, yes, it renders, but it's so faint I can hardly see it, it's probably a layer issue).
I wrote this to fix it, because P.U.R.E.'s relationship between metal and the maps has changed, and I needed to very clearly tell players where they were already mining, and this does it.
To make use of this, Units need to have a customParam, "miner", with a value of "yes" (or change this to however you want, obviously- I tend to avoid using UnitDef values for most things).
At any rate, it was a 20-minute little thing, so if anybody likes it, great, if not, no biggie.

end
end
end
function widget:DrawWorldPreUnit()
mode = GetMapDrawMode()
if mode == "metal" then
unitIDList = GetVisibleUnits(-1,3000,false)
if unitIDList[1] ~= nil then
for _,unitID in ipairs(unitIDList) do
if (IsUnitVisible(unitID)) then
id = GetUnitDefID(unitID)
if MinerList[id] then
x,y,z = GetUnitPosition(unitID)
glLineWidth(10)
glColor(1,0,0,1.0)
glDrawGroundCircle(x,y,z,radius,123)
glColor(1,0,0,0.75)
glDrawGroundCircle(x,y,z,radius2,123)
glColor(1,0,0,0.5)
glDrawGroundCircle(x,y,z,radius3,123)
end
end
end
end
end
end
If that means it's not taking real metal into account, but is just using that value... then I'll leave it that way, then you can't see enemy metal use very well.
