Hola,
¿Alguien sabe que acción puedo poner en la colisión de dos objetos para sustituirla por el evento target?
Estoy practicando con la puntuación de un juego que puntúa cuando pulsamos con el dedo sobre el objeto:
Código lua:
Ver originallocal function onTouch( event )
print(event.phase)
if event.phase == "began" then
score.add(event.target.value)
timer.performWithDelay(10, function() event.target:removeSelf(); end, 1)
end
return true
end
...y la quiero cambiar cuando colisiona:
Código lua:
Ver originallocal function onCollision_2(event)
if event.phase == "began" then
local agro = event.object1
local hit = event.object2
if agro.type == "crate" and hit.type == "grass" then
elseif agro.type == "grass" and hit.type == "crate" then
--código para ejecutar la acción de la colisión y añadir puntos
grass.isVisible = false
end
end
end
Runtime:addEventListener("collision", onCollision_2)
Este sería el script completo:
Código lua:
Ver originallocal centerX = display.contentCenterX
local centerY = display.contentCenterY
local _W = display.contentWidth
local _H = display.contentHeight

bkg.y = 240
local grass = display.newImageRect("grass.png", 360, 40)
grass.x = centerX
grass.y = _H - 68
grass.type = "grass"
physics.addBody( grass, "static", { friction=0.5, bounce=0.3 } )
local function newCrate()
rand = math.random( 100 )
local crate
if (rand < 60) then
crate = display.newImage("crate.png");
crate.x = 60 + math.random( 160 )
crate.y = -100
physics.addBody( crate, { density=0.9, friction=0.3, bounce=0.3} )

crate.type = "crate"
end
local function onTouch( event )
print(event.phase)
if event.phase == "began" then
score.add(event.target.value)
timer.performWithDelay(10, function() event.target:removeSelf(); end, 1)
end
return true
end
crate:addEventListener( "touch", onTouch )
end

end
end
return true
