Flappy löve (Works on android! (theoretically))

[veethree]

This was going to happen eventually and you all know it. A flappy bird clone.

It's pretty minimal at the moment, But i think it plays nicely. You just have an infinite game loop, Press any key to start, And the player starts falling, press up, W or space to "flap". If/when you crash into one of the pipe things, You die and the game starts over.

Note that it uses a shader and a canvas. If your machine doesn't support those, Too bad. (If you really want to play this and don't support shaders/canvases, You can edit the code yourself, all the shader stuff happens in game:draw in game.lua)

Enough text, Here's screenshots: (Outdated)

You'll be seeing this alot


In case you couldn't tell the design is based off the old forum banner.

I do not recommend looking through the code. Might give you a headache. I wasn't exactly thinking straight while coding this. (if you know what i mean)

I was just about to do this
Nice game.

Nice game.

Saw 2 bugs. When you lose and hit space bar the gravity won't work, obstacles don't spawn and score is being counted
The background has a small gap that keeps blinking when the screen moves.

Can you FOSS this, so I can offer pull requests to make this an android game? ;)

Sure! What's FOSS?

Talked to veethree, he's pushed code to github!

You have to press a key (any) to start the game. And i fixed the score being counted, Latest version on github. (link in the OP)

This is great! I've been playing around with your code a bit, and in the process of adapting it I've run into a little problem. I don't know if I'm better off asking in the help forum but my code is mostly based on yours so, I figured I'd just ask here.

For collision testing and debugging purposes I was trying to make the player change color while overlapping one of the walls but it doesn't seem to be working. I can make change the color upon collision, but then it doesn't revert to the original color when it is not colliding. Would you (or anyone else) mind taking a look? This is from main.lua

Code: Select all

-- collision, loop through walls
  for i,v in ipairs(wall.array) do
    for _,s in ipairs(v) do
      if checkCollision(player.x, player.y, player.size, player.size, s.x, s.y, s.width, s.height) then
        player.collision = true
      else
        player.collision = false
      end
    end    
  end

If I remove the else condition , the player will change color but not change back. With this else condition nothing happens.

Couldn't tell you why, But that logic doesn't usually work. Try something like this:

Code: Select all

  player.collision = false
  for i,v in ipairs(wall.array) do
    for _,s in ipairs(v) do
      if checkCollision(player.x, player.y, player.size, player.size, s.x, s.y, s.width, s.height) then
        player.collision = true
      end
    end    
  end

@Reef, after finding a collision, you set the collision boolean, but then continue looping through the other values. So if there's any other value in the table where it doesn't collide, then the boolean is set back to false.

You could use a break command in the for loops, to jump out of the loops after the player.collision is set to true. Unless you need to call checkCollision on all tiles (even when you already know that it collided with one), then veethree's way is the best way to go.
