Error simple code tap

Hi, I have a fail in my code, sure is a simple fail, but I cant see the solution.

The code is:
 

Código:
function player.atk12()

if player.atk1 >= 300 then
player.atk1 = player.atk1 - 300
player.q.text = player.atk1
VidaB = VidaB - 30
boss.vida.text = VidaB
        
if player.atk1 >= 300 then
player.atk.isVisible = false
     player.atk_.isVisible = true
end
if player.atk1 < 300 then
player.atk.isVisible = true
     player.atk_.isVisible = false
end
end

end
    
    
player.atk_:addEventListener( “tap”, player.atk12 )

The Question is, I have a Points in the var player.atk1, and when this var is 300, I can TAP in image for attack, but the problem is that when I have 600 points in player.atk1, I TAP one time in image and not lose 300 points with one attack, I lose 600 points and attack two times with only one click.

Someone can help me for Attack only one time with one tap in image?

Sorry for my english, im Spanish.

regards.

Are you sure that you are only adding this event listener once? 

player.atk\_:addEventListener( "tap", player.atk12 )

If you add it twice by mistake, then it will be called twice when you tap.

Try adding

 print("tap")

 above the 

if player.atk1 \>= 300 then

 to see if it prints twice when you tap once.

You need to add this to the end of your tap function:

return true
