So i´ve been trying to code my first game! I have random spawning circles and a rectangle. I want to make the circles to disappear after they collide with the rectangle. Can anyone help me? Thanks!
Can you post some code that we can build off of? Thanks!
Edit: ** Corrected placement of return in function **
Agreed, understanding how you make your collision handler would help.
That said, I always use table listeners and would do it this way:
-- Answer is pseudo-code mixed with actual code... local circ = display.newCircle( ... ) ... function circ.collision( self, event ) if( event.phase == "began" ) then self:removeEventListener("collision") timer.performWithDelay( 1, function() display.remove(self) end ) return false end end circ:addEventListener( "collision" )So this is the full code:
[lua]
local physics = require(“physics”)
physics.start()
halfW = display.contentWidth*0.5
halfH = display.contentHeight*0.5
–Background
local bkg = display.newImage(“bkg.png”, halfW, halfH)
–Score
score = 0
scoreText = display.newText(score, halfW, 260, native.systemFont, 150)
–Rectangle
rect = display.newRect( 540, 1800, 300, 75 )
rect:setFillColor(255)
rect.myName = “rect”
physics.addBody(rect, “static”, {density=1.0, friction = 0.5, bounce = 0.0} )
–Rectangle movement
function rect:touch(event)
if event.phase == “began” then
self.markX = self.x
elseif event.phase == “moved” then
local x = (event.x - event.xStart) + self.markX
self.x = x
if self.x > 930 then self.x = 930 end
if self.x < 150 then self.x = 150 end
end
return true
end
rect:addEventListener( “touch”, rect )
–circle
local function SpawnCircle()
circle = display.newCircle ( math.random(30,1890), 0, 30)
circle:setFillColor(1)
physics.addBody( circle, “dynamic”,{density=1.0, friction = 0.5, bounce = 0} )
end
timer.performWithDelay(1000, SpawnCircle, 0)
[/lua]
I want to make so that the ball falling hit the rectangle and disappear, and when a single ball hit the rectangle, the score ups in one point. can anyone help me? I’ve been stuck for days…
In your code, I don’t see any type of collision detection included. Did you look at the response by @roaminggamer in this thread?
