insantly stop a body in love.physics

[Doctory]

how would i stop a body in love.physics? im making a platformer game and i need the player not to slide around

[ivan]

For sliding over platforms we use friction (from 0 to 1)
For lowering the velocity over time (even while in the air) we use linarDamping and angularDamping (from 0 to positive infinity)
Another option is to manually set the linear/angular velocity to 0 but this will produce strange looking collisions.

when i use :setFriction(1) it throws an error on me that its a nil value

[arampl]

Maybe object before colon is not fixture?

[Doctory]

it most certainly is a fixture

[arampl]

Then more code needed. ":setFriction(1)" is not enough. What else can give you nil? Of course not "1". And "setFriction" is the right name for the method.

According to the wiki, only Shapes, Fixtures and Contacts have setFriction methods; the code should only return an error about that being nil if the object's not one of those.
You could post in the relevant piece of code as arampl mentioned.

Code: Select all

player.body = love.physics.newBody(world, player.spawnpoint.x, player.spawnpoint.y, "dynamic")
player.shape = love.physics.newRectangleShape(20, 20)
player.fixture = love.physics.newFixture(player.body, player.shape):setUserData("player")

putting setFriction on shape or the fixture just returns a nil error

[arampl]

I think you should split the last line into two:

Code: Select all

player.fixture = love.physics.newFixture(player.body, player.shape)
player.fixture:setUserData("player")

Then you'll be able to use setFriction with player.fixture.
