I’m using this function to move the circle!

How can i display the invisible line that i draw to applay the impulse to the circle???

  physics.start()    function circleT(event) if event.phase == "began" then display.getCurrentStage():setFocus(circle)   else if  event.phase == "ended" then   circle:removeEventListener("touch", circleTouch)   circle:applyLinearImpulse(event.xStart - event.x, event.yStart - event.y, circle.x, circle.y) display.getCurrentStage():setFocus(nil)           end end end     circle:addEventListener("touch", circleT)

Try this:

require("physics") physics.start() physics.setGravity(0,0) physics.setDrawMode("hybrid") local ball = display.newCircle( display.contentCenterX, display.contentCenterY, 40 ) physics.addBody( ball, "dynamic", { density=1, radius=40 } ) function ball:showLine(e) if (ball.line) then ball.line:removeSelf() ball.line = nil end if (e) then ball.line = display.newLine( e.xStart, e.yStart, e.x, e.y ) ball.line.width = 5 end end function ball:touch(e) if (e.phase == "began") then display.getCurrentStage():setFocus( ball ) ball.hasFocus = true ball:showLine(e) return true elseif (e.target.hasFocus) then if (e.phase == "moved") then ball:showLine(e) else ball:showLine() ball:applyForce( e.xStart-e.x, e.yStart-e.y, ball.x, ball.y ) end return true end return false end ball:addEventListener("touch",ball)
