Question

In my application I want an object to slide and jump on touch began event in Corona. Although I am successful in implementing both slide and jump on touch ended event, but making event phase at began I can’t do slide.

I use the following code for sliding and jumping:

function touched( event )
  if(event.phase == "ended") then
    if(event.x - event.xStart > 70) then
      sliding = true;
      offGround = true; 
    else
      boy:applyLinearImpulse(0, -0.44, boy.x, boy.y)
      offGround = true;
    end
  end
end

Answer 1

I have done this. I use moved phase and mark a boolean active on move phase and call a timer function at began. Here is my code.

function Action()
    if(Slide == true)then
        Slide = false;
        sliding = true;
    else
        if(jump == true)then
            meter = -0.54
            boy:applyLinearImpulse(0, meter, boy.x, boy.y)
        end
    end
end

function touched( event )
    local phase = event.phase
    print(phase)

    if(phase == "moved")then
        Slide = true;
        jump = false;
        print("Boy is Sliding")
    end
    if(phase == "began")then
        if  Slide == false then
            print("Boy is not Sliding")
            jump = true
        end

        timerNew = timer.performWithDelay(100 , Action , 1)
    end
end
