Untested e-mail Lingo:
property pMySprite
property pTargetSprite
property pPctMatch
property pMyArea
on init me, targetSprite
pTargetSprite = targetSprite
pPctMatch = 0.8
pMySprite = sprite(me.spriteNum)
pMyArea = float(pMySprite.width * pMySprite.height)
end
on checkDrop
combinedRect = union(pMySprite.rect, pTargetSprite.rect)
totalArea = float(combinedRect.width * combinedRect.height)
if ((totalArea * pPctMatch) <= pMyArea) then
return TRUE
else
return FALSE
end if
end checkDrop
Test, debug, add comments, and let me know how it works.
Cordially,
