So let say I setFillColor two objects:
obj1:setFillColor(math.random(),math.random(),math.random()) obj2:setFillColor(math.random(),math.random(),math.random())
How can I check whether both objects have similar colors?
use variables which you need to keep track of and can compare
havent seen a direct way of accessing a display objects color settings
local c1=math.random()
local c2=math.random()
local c3=math.random()
local c4=math.random()
local c5=math.random()
local c6=math.random()
obj1:setFillColor(c1,c2,c3)
obj2:setFillColor(c4,c5,c6)
if c1==c4 then etc etc
there is also a different approach that may be easier to handle with numerous objects
in lua you can attach any property you like to a display object, so you could do this…
obj1=display.newImageRect()
obj1.r=math.random()
obj1.g=math.random()
obj1.b=math.random()
obj1:setFillColor(obj1.r,obj1.g,obj1.b)
obj2=display.newImageRect()
obj2.r=math.random()
obj2.g=math.random()
obj2.b=math.random()
obj2:setFillColor(obj2.r,obj2.g,obj2.b)
if obj1.r==obj2.r then etc etc
EDIT - adding any property you like to a display object is a very powerful and useful ability, for example:
obj1.status=“moving”
obj1.inFocus=false
obj1.tag=“my current object”
anything goes really, and as long as your object exist, so do the variables.
when the object is removed, so does all attached properties…nifty!
Wow amazing! I will try this out
