(experimental) make the mysterious borders around land/hats/etc that appear on zoom vanish
note: not applied to everything yet
note: I'll probably merge the two functions that do the same thing (one for 1darray, one for 2darray representation of pixels) into a single function
-- Library for miscellaneous utilitiy functions
-- Check if a gear is inside a box
function gearIsInBox(gear, x, y, w, h)
gx, gy = GetGearPosition(gear)
if gx >= x and gy >= y and gx <= x + w and gy <= y + h then
return true
end
return false
end
-- Check if a gear is inside a circle
function gearIsInCircle(gear, x, y, r, useRadius)
gx, gy = GetGearPosition(gear)
if useRadius then
r = r + GetGearRadius(gear)
end
if r ^ 2 >= (x - gx) ^ 2 + (y - gy) ^ 2 then
return true
end
return false
end
