Flashing blip

[Dzsozi (h03)]

Hello everyone! I was thinking if is it possible to make the square blip flashing? So it changes it's color from red to blue and from blue to red in every 1.5 second. How is this possible? Could somebody help me please?

setTimer 
getBlipColor 
setBlipColor 

Put it on a function which checks or the color is red or blue. If it is blue, then make it red, if it is red, make it blue. Also check or the blip actually exists and put the timer on 1500 seconds (=1,5 seconds) and put it on unlimited repeats (=0).

I don't know how to make it, I've started it, but I realised that it's not going to work. Here's what I started to make, but I don't know how to finish it, or how to make it working.

  
blue = 5, 120, 250 
red = 255, 0, 0 
  
function checkColor() 
    if blue then 
        createBlip ( x, y, z 0, 2, red, 255, 0, 150) 
    elseif red then 
        createBlip ( x, y, z 0, 2, blue, 255, 0, 150) 
    end 
end 
setTimer ( checkColor, 1500, 0 )

-- create a blue blip 
local blip = createBlip ( x, y, z 0, 2, 5, 120, 250) 
local color = false 
  
function checkColor() 
    if color then 
        setBlipColor(blip, 5, 120, 250) 
    else 
        setBlipColor(blip, 255, 0, 0) 
    end 
  
    color = not color 
end 
setTimer ( checkColor, 1500, 0 )
