    How can I fly with setLinearVelocity?

    edited February 2014 in General questions
    Now my game can only fly exactly high because I used setLinearVelocity(0,-10) once player tap.

    Check it out

    But I want the hero in my game can fly higher when I press longer and fly not so high when I quickly tap.

    Sorry for my English. Anyone can help me? Thanks.

      If you are after something more similar to a flappy bird effect, you can achieve it by something like this:
      function jump()
    local x, y = body:getPosition()
    body:applyLinearImpulse(0, -10, x, y)
end
 
local timer = Timer.new(200)
timer:addEventListener(Event.TIMER, jump)
 
stage:addEventListener(Event.MOUSE_DOWN, function()
    jump()
    timer:start()
end)
 
stage:addEventListener(Event.MOUSE_UP, function()
    timer:stop()
end)

      No, I don't want the flappy bird effect. The effect is more like Mario style jump.

      Well either it is flying or jumping all depends on tweaking the velocities and gravity.
      The approach is the same.

      ;)
