Need some help with Physic module ?

[Neolitik]

Hello any ,

I' m on the " physics way" in love.
I want make a Body , Can jump and move ....
But in my code , if i jump my body dont conserve right or left move !
I had search in the LovelBigPlantet code but i m dont understand all
i read this : --get the velocity, process the input, and set it, preserves untouched velocity..
i try make but dont work
my code :

Code: Select all

function update(dt)
local x,y=Circle:getVelocity()
Circle:setSleep( false ) 
if love.keyboard.isDown(love.key_right) then
x= 500
end
if love.keyboard.isDown(love.key_left) then
x= -500
end
if love.keyboard.isDown(love.key_space) then
y= -500
end
Circle:setVelocity(x,y)
World:update(dt)
end

any solution welcome thank for all !

The code looks correct for a simple set-velocity jumping system.
Could you be more specific about what the problem is?

As in, what do you mean by, "It doesn't conserve left or right movement"?

Could you post more code? It looks pretty correct to me too.

Do you mean that you can turn around in mid-air?
Cause, if that's the problem, you would have to put in a check for whether you're in the air too before setting the x velocity.

My guess is, that, if you're making a platformer-type game and using the physics module that you found your guy sliding around on the floor like he was in a Super Mario Bros. 2 ice level; and perhaps you wrote some code to kill the X velocity when left and right where not being pressed... I'm guessing this because i've just started with Love and not 20 minuets ago did exactly the same thing

If this is the case, perhaps, check that the player sprite is not colliding with the floor (i.e is in the air) before killing your x velocity.
