Physics and images (HardonCollider)

[Jeen]

Hello.
I use HardonCollider for collision detection and it works pretty good. But I need to draw a player sprite and move it with its bounding box together. How can I do this?
Thank you .

Probably the easiest way would be to use shape:center() to get the shape center and use the numbers returned to draw the sprite at the right place.

Thanks, it works, but the sprite draws at left-bottom corner of the bounding box. How can I fix it? Also, if I try to add other arguments to love.graphics.draw, the sprite doesn't move down with the box, only on x axis.

Code: Select all

function love.draw()
     love.graphics.draw(heroImage, hero:center(x))
end

hero is:

Code: Select all

hero = collider:addRectangle(x,y,16,16)

Code: Select all

function love.draw()
     local hx, hy = hero:center()
     love.graphics.draw(heroImage, hx - 8, hy - 8)
end

(The negative 8 is 1/2 your hero's width and height.)

You're probably better off using the origin arguments (ox and oy), because they correctly handle rotation as well.
