Jumpy Blocks

[LemonLake]

I'm having this issue with physics. I have static tiles, and dynamic tiles that start frozen. Whenever I hit the dynamic tiles with the wrecking ball, they move as expected. However, when they're on the ground they start jumping and sliding about, and I can't figure out why. Can anyone help me?

Moving tile codeÄ

Code: Select all

				local newobj={}
				newobj.body = love.physics.newBody(world,i*32-32,j*32-32,"dynamic")
				newobj.shape = love.physics.newRectangleShape(32,32)
				newobj.fixture = love.physics.newFixture(newobj.body, newobj.shape)
				newobj.body:setAwake(false)
				newobj.id = layout[j][i]
				newobj.fixture:setFriction(100)
				newobj.fixture:setDensity(100)
				newobj.body:setMass(0.01)
				newobj.fixture:setCategory(2)
				newobj.fixture:setMask(2)

Static tile codeÄ

Code: Select all

				local newobj={}
				newobj.body = love.physics.newBody(world,i*32-32,j*32-32,"static")
				newobj.shape = love.physics.newRectangleShape(32,32)
				newobj.fixture = love.physics.newFixture(newobj.body, newobj.shape)
				newobj.fixture:setFriction(100)

Wrecking ball codeÄ

Code: Select all

	ball.body = love.physics.newBody(world,player.x,player.y+96,"dynamic")
	ball.shape = love.physics.newCircleShape(15)
	ball.fixture = love.physics.newFixture(ball.body, ball.shape)
	ball.body:setMass(500)

Crane codeÄ

Code: Select all

	player.body = love.physics.newBody(world,player.x,player.y,"kinematic")
	player.shape = love.physics.newRectangleShape(2,2)
	player.fixture = love.physics.newFixture(player.body, player.shape)
	player.fixture:setMask(2)

The crane and ball are connected withÄ

Code: Select all

ropeJoint = love.physics.newRevoluteJoint(player.body, ball.body, 1, 1, 16, 16, 16, false)

Notes:
Up, down: move crane up/down
Left, right: move crame left/right

Move to the right to find the building to wreck, the movable blocks are reddish

Can you try changing the Restitution of the fixtures?

https://love2d.org/wiki/Fixture:getRestitution

That's what determines how they bounce, and I don't think you're setting it, so it's just using the default. I'm not sure what kind of value you need and I'm not near my development computer to try, but either something really low or something really high should make them stop jumping around.

I played the game, and couldn't see anything wrong Strange. But, the games BGM is awesome!

Unfortunately, setting the restitution was not the issue. I found out that the rectangles are denying the laws of physics and rotating without trigger as if they were wheels. Fixing the rotation solved it, however I want them to be rotatable. Any ideas?
