Thanks, I'm glad it worked well for you!megalukes wrote:I was struggling with collisions for a while (using HC and programming my own module), but this lib saved me from a lot of trouble I was going through. Thank you very much.
Code: Select all
world:update(player, player.x+6, player.y+6)Code: Select all
local goalX = player.x + player.addX
local goalY = player.y + player.addY
local actualX, actualY, cols, len = world:move(player, goalX, goalY, playerFilter)
player.x, player.y = actualX - player.addX, actualY - player.addYFor things like that, I tend to not mess with the physics box itself, rather I draw the sprite with an offset in a :draw function. Usually you'll define an offset when the object is initialized, and subtract that from the rendering function itself.megalukes wrote:Is there a way I can edit the rectangle's position inside the world?
For instance, I need the bounding box to be 6 pixels to the right and down to make it work with my graphic, so I did this:
However, this seems to bug my collision detection. It acts as if the rect was still in player.x, player.y. Is there a better way to do that? I didn't want to change the graphic because I use a different collision system for the tilemap, so I'm stuck.Code: Select all
world:update(player, player.x+6, player.y+6)
EDIT: I found a way to do it. I thought I should use :update somewhere else with adjustment coords, so I tried to add them in the :move call.
