This is the code to hit the ball from simple pool example, with a few changes.
---------------------------------------------Hit--------------------
-------------------------------------------the ball--------------------
local cueball = display.newImage( "levelimages/golfball.png" )
cueball.x = 57; cueball.y = 150
cueball.xScale = 1
cueball.yScale = 1,
physics.addBody( cueball, {radius = 6} )
cueball.linearDamping = .9
cueball.angularDamping = .8
cueball.isBullet = true -- force continuous collision detection, to stop really fast shots from passing through other balls
cueball.color = "white"
local target = display.newImage( "target.png" )
target.x = cueball.x; target.y = cueball.y; target.alpha = 0
target.xScale = 1
target.yScale = 1
-- Shoot the cue ball, using a visible force vector
local function cueShot( event )
local t = event.target
local phase = event.phase
if "began" == phase then
display.getCurrentStage():setFocus( t )
t.isFocus = true
-- Stop current cueball motion, if any
t:setLinearVelocity( 0, 0 )
t.angularVelocity = 0
target.x = t.x
target.y = t.y
startRotation = function()
target.rotation = target.rotation + 1
end
Runtime:addEventListener( "enterFrame", startRotation )
local showTarget = transition.to( target, { alpha=0.4, xScale=0.2, yScale=0.2, time=200 } )
myLine = nil
elseif t.isFocus then
if "moved" == phase then
if ( myLine ) then
myLine.parent:remove( myLine ) -- erase previous line, if any
end
myLine = display.newLine( t.x,t.y, event.x,event.y )
myLine:setColor( 255, 255, 255, 50 )
myLine.width = 8
elseif "ended" == phase or "cancelled" == phase then
display.getCurrentStage():setFocus( nil )
t.isFocus = false
local stopRotation = function()
Runtime:removeEventListener( "enterFrame", startRotation )
end
local hideTarget = transition.to( target, { alpha=0, xScale=1.0, yScale=1.0, time=200, onComplete=stopRotation } )
if ( myLine ) then
myLine.parent:remove( myLine )
end
-- Strike the ball!
t:applyForce( ( event.x - t.x ), ( event.y - t.y ), t.x, t.y )
audio.play(hitsound)
end
end
-- Stop further propagation of touch event
return true
end
And this is the timer that resets the cueball
[code]
local function listener( event )
if(right == “true”) then
cueball.x = 57
cueball.y = 150
print( “listener called” )
right = “false”
end
end
timer.performWithDelay( 100, listener, -1 )
