A huge issue with collision

[tommyroyall]

Hey, so I made a simple game, and I create objects like this:

Code: Select all

  objects.player={}
  objects.player.body=love.physics.newBody(world,SPAWN_X,SPAWN_Y,'dynamic')
  objects.player.shape=love.physics.newCircleShape(25)
  objects.player.fixture=love.physics.newFixture(objects.player.body,objects.player.shape,1)
  objects.player.fixture:setRestitution(0.9)

And I create blocks with a function, called:

Code: Select all

function addBlock(x,y,state)
  blockcount=blockcount+1
  x=x*METER
  y=y*METER
  block_width=METER
  block_height=METER
  objects.block[blockcount]={}
  objects.block[blockcount].body=love.physics.newBody(world,x,y,state)
  objects.block[blockcount].shape=love.physics.newRectangleShape(block_width,block_height)
  objects.block[blockcount].fixture=love.physics.newFixture(objects.block[blockcount].body,objects.block[blockcount].shape,1)
end

Now, there's no issues with the variables as far as I know, but what would cause them to simple not register as colliding? Also, do I need to do anything with the world:setCallbacks()? I used it, seems kind of useless . . .

Also, I didn't supply a .love because this is a fairly large/complex project, and collision just magically died -_-. If you want it though, I will post it.

here's a short checklist for you:
1. check if you use METER correctly
2. check if you use world:setMeter() correctly (if you use it at all)
3. check the dimensions of your world
4. check if you update the world correctly
5. try to visualize all your shapes

you don't need to use world:setCallbacks() just to enable collisions, you use it only to run some code when two bodies collide.
