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:
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
…y la quiero cambiar cuando colisiona:
local 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)
