Hello,
Does anyone know what action I can put in the collision of two objects to replace the target event?
I’m practicing with the score of a game that rate when you press with your finger on the object:
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
… and I want to change when it collides:
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 --Code to execute the action of the collision and add items end end end Runtime:addEventListener("collision", onCollision\_2)
This is the complete script:
local centerX = display.contentCenterX local centerY = display.contentCenterY local \_W = display.contentWidth local \_H = display.contentHeight local physics = require( "physics" ) physics.start() local widget = require( "widget" ) local score = require( "score" ) display.setStatusBar( display.HiddenStatusBar ) local bkg = display.newImageRect( "bkg\_clouds.png", 360, 480) bkg.x = centerX 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.value = 50 crate.type = "crate" elseif (rand \< 80) then crate = display.newImage("crateB.png"); crate.x = 60 + math.random( 160 ) crate.y = -100 physics.addBody( crate, { density=1.4, friction=0.3, bounce=0.2} ) crate.value = 100 crate.type = "crate" else crate = display.newImage("crateC.png"); crate.x = 60 + math.random( 160 ) crate.y = -100 physics.addBody( crate, { density=0.3, friction=0.2, bounce=0.5} ) crate.value = 500 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 local scoreText = score.init({ fontSize = 20, font = "Helvetica", x = display.contentCenterX, y = 20, maxDigits = 7, leadingZeros = true, filename = "scorefile.txt", }) local function saveScore( event ) if event.phase == "ended" then score.save() end return true end local saveButton = widget.newButton({ width = 200, height = 64, x = display.contentCenterX, y = display.contentHeight - 32, label = "Save Score", labelColor = { default = { 1, 1, 1 }, over = { 0, 0, 0 } }, fontSize = 32, onEvent = saveScore }) local function loadScore( event ) if event.phase == "ended" then local prevScore = score.load() if prevScore then score.set(prevScore) end end return true end local saveButton = widget.newButton({ width = 200, height = 64, x = display.contentCenterX, y = display.contentHeight - 64, label = "Load Score", labelColor = { default = { 1, 1, 1 }, over = { 0, 0, 0 } }, fontSize = 32, onEvent = loadScore }) local dropCrates = timer.performWithDelay( 1000, newCrate, 100 ) -------------------------------------------COLISION---------------------------------------- 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 --Code to execute the action of the collision and add items end end end Runtime:addEventListener("collision", onCollision\_2)
