Collision Detection

Games
#1

So I have a game that takes a image and has these other images falling down with a spawn function and a timer. I want to know how to add collision. the main character is controlled by touch.

local object  
local fingerTouch  
local background  
  
  
local physics = require("physics")  
physics.start()  
physics.setGravity(0, 4)   
  
background = display.newImage("bg.png")  
  
local HUD = display.newImage("hud.png")  
  
local score = 0  
local scoreText  
scoreText = display.newText(score, 150, 10, Helvetica, 50)  
local function scoreTimer()  
score = score + 1  
scoreText.text = score  
if (score == 30) then  
score = score + 10000  
scoreText.text = score  
end  
end  
scoretmr = timer.performWithDelay(1000,scoreTimer,0)  
object = display.newImage( "rainbowdash.png" )  
object.x = 160  
object.y = 400  
   
fingerTouch = function(e)  
 if e.phase == "moved" then  
 object.x = e.x  
 object.y = e.y  
 end  
   
end  
   
   
Runtime:addEventListener( "touch", fingerTouch )   
  
local function spawnCrate()  
local balloon = display.newImage("red.png");  
balloon.x = math.random(320);  
balloon.y = -100;  
physics.addBody( balloon, { density=2.0, friction=0.5, bounce=0.3 } )  
end  
timer.performWithDelay(650,spawnCrate,800000000)

That is what I have written so far? Can anyone help? [import]uid: 39840 topic_id: 17370 reply_id: 317370[/import]

There’s a very newbie friendly part showing exactly how to do collision detection :slight_smile: [import]uid: 52491 topic_id: 17370 reply_id: 65761[/import]
