on collision, the entire spawned enemies on the screen are removed instead of only one.
here is the code
[code]
bricks1 = {}
local n = 0
– the bullet animation goes here
local function throwBrick2()
n = n + 1
– goes here
bricks1[n] = display.newImage(“bomb.png”, plane.x + 10 , plane.y + 2)
physics.addBody( bricks1[n],{ density=0, friction= 0, bounce=0 } )
startListening()
– remove the “isBullet” setting below to see the brick pass through cans without colliding!
bricks1[n].isBullet = true
bricks1[n].angularVelocity =0
bricks1[n]:applyForce( 5000, 0, bricks1[n].x, bricks1[n].y )
end
here is the enemy
dudes22 = {}
local function makeDude3()
dude22 = display.newImageRect(“enemyblack13.png”, 200, 200)
dude22.xScale = .5
dude22.yscale = .1
dude22.x, dude22.y = math.random(500, 600), math.random(50, 280)
– change to 50 70
dudes22[#dudes22+1] = dude22
end
local function listener3(event)
for i, v in pairs(dudes22) do
n = n + 1
physics.addBody( dudes22[i], “kinematic” ,{density=10000, friction=0, bounce=0,radius= 35} )
if dudes22[i].x <1 then
dudes22[i]:removeSelf()
dudes22[i] = nil
else
local speed = 5
dudes22[i].x = dudes22[i].x - speed
– timer.performWithDelay( 500, throwBrick1, 1 )
– startListening()
end
end
end
timer.performWithDelay(1000, makeDude3, 500)
here is collision
function startListening()
– if egg1 has a postCollision property then we’ve already started listening
– so return immediately
for k, v in next, bricks1 do
if bricks1[k].postCollision then
return
end
end
local function onEggCollision ( self, event )
– uses “postSolve” event to get collision force
print( "force: " … event.force )
– Crack this egg if collision force is high enough
if ( event.force ==0 ) then
for k, v in next, dudes22 do
dudes22[k]:removeSelf()
– table.remove(dudes22[k],k)
dudes22[k] = nil
– After this egg cracks, it can ignore further collisions
–self:removeEventListener( “postCollision”, self )
end
return true
end
end
– Set table listeners in each egg to check for collisions
for k, v in next, dudes22 do
dudes22[k].postCollision = onEggCollision
dudes22[k]:addEventListener( “postCollision”, dudes22[k] )
end
end
