Hello!

With help from the wiki i manage to get my character to jump! but he can't jump while he is moving...try to press space while you hold "d"...

How can i make it jump while moving?

Also, as you can in the game, the character just passes through the crate...how can i make the crate to have a mass and be an obstacle to the character?

I attached the .love

Ok it's very simple, in love.update make a function called, for example, walking.speed and jumping speed linked to your velocity. So in love.update write

Code: Select all

walking.speed, jumping.speed=getLinearVelocity

Then in love.update, when you tell your character to jump, just do

Code: Select all

character:setLinearVelocity(walking.speed, -1000)

-1000 of course being your jumping speed.

As far as I can see, that works.

Note that you don't actually use the character's body. Get rid of objects.char.x and objects.char.y. Instead, use love.physics: for getting the character's position to draw it, use objects.char.body:getX and objects.char.body:getY. Instead of changing the x-position of the character directly in love.keypressed, use objects.char.body:applyLinearImpulse, and do the same for jumping.

i am telling my character to jump in love.keypressed so i added in the love.update the

Code: Select all

walking.speed, jumping.speed=getLinearVelocity

and in love.keypressed the

Code: Select all

character:setLinearVelocity(walking.speed, -1000)

but i guess i'm doing something wrong

@Robin

something like that?

Code: Select all

if key == "a" then
    objects.char.body:applyLinearImpulse( 10, 0 )
    char_direction = "left"
elseif key == "d" then
    objects.char.body:applyLinearImpulse( -10, 0 )
    char_direction = "right"
end

clepto you are doing something wrong, the getlinearvelocity, you have to do like character:getlinearvelocity, so if your character body is bloublou, it will be bloublou:getlinearvelocity. sorry
