LÖVE

hello I'm making a small platformer and I'm using kikito's bump for collisions.

It's going well however right now I can't get jumping right. The problem is that, you can jump up walls indefinitely. I'm trying to make it behave much more traditionally, as it should.

So how do I make the jump not stick to everything essentially?

Use arrows to move, x to jump

Thanks, I attached the love for reference.
Love 0.10.0 is necessary for it to work properly.

You are setting your y_velocity to zero and flipping your on_ground to True for EVERY collision. So when you are next to a wall, the game thinks you are on the ground. Instead do with goalY being 1 pixel below your current position. player.yvel = 0 only if that throws collisions.

Change: To:

I know it wasn't your actual intention, but I find that stickiness fun

Code: Select all

local actualX, actualY, cols, len = world:check(item, goalX, goalY, <filter>)

with goalY being 1 pixel below your current position. player.yvel = 0 only if that throws collisions.

Change:

Code: Select all

  for i=1,cols_len do
    player.yvel = 0
  end

To:

Code: Select all

  local actualX, actualY, cols, cl = world:check(player, player.x, player.y+1)
  for i=1,cl do
    player.yvel = 0
  end

Great, I see now. this was exactly what I needed, much thanks!

Haha, funny you say that I thought the same thing.

Here's an unrelated issue, I'm having a strange problems as a repercussion of my implementation of player velocity
Right now, when the player collides with anything it runs this code
this makes the player move properly, however the issue is that if I set yvel to 0 then every time it touches an object set to cross, the player keeps having his yvel reset, so he very slowly moves through objects with the cross filter.

does anybody have any ideas on how I could make the cross filter work properly with my velocity?
