setActivePixels:

1. Filter blocks which Xposition is x > 2 or x < 10
2. Create a Pixels set based on current active pixels
3. Remmove previous brick from Pixels
4. Add current brick to Pixels A. if in aming mode (pixel.y === 1) just add new brick to the set (there is no risk of colision) B. if in drop mode (pixel.y > 0) check if there is a colision a. if setBrickPixel.y === curBrickPixel.y + 1 and setBrickPixel.x === curBrickPixel.x add pixel to set, quit the set loop and test another curPixel. b. if setBrickPixel.y !== curBrickPixel.y + 1 add pixel to set, quit the set loop and test another curPixel.
5. Save in state: current brick as prevBrick, Pixels as activePixels
6. If (pixel.y > 13) startAiming()

detectColision:

return true if there is colision with the stack

1. Check if pixel.y + 1 is contained in Pixels set

startAiming:

// should be triggered at start, if brdck hit the flor or if there is a colision

1. Clear drop interval
2. Reset Xposition, Yposition, prevBrick
3. Start aiming in intervals

aim (3 blocks):

variables: Xposition, startLeft, moveRight, counter, brickLength

1. Change X position depending on direction if moveRight Xposition + 1 if !moveRight Xposition - 1
2. Save changed X position in state
3. Check if direction should be changed If Xposition is 9, change direction to left If Xposition is 1, change direction to right
4. Add 3 blocks to the newBrick array (first bolock X position is equal to current X position, two other are moved by +1 and +2)
5. setActivePixels

drop (3 blocks):

variables: Xposition, Yposition, brickLength

1. Clear drop interval when Y > 13
2. Change Y position by + 1
3. Save changed Y position in state
4. Add 3 blocks to the brick array (first bolock X position is equal to current X position, two other are moved by +1 and +2. Y positon is equal to current Y positon) x. Detect colision a. If set
5. setActivePixels

Behaviour

Brick Pixels should fall untill each of them collide with either bottom or pixels from stack. I it is level 0 all pixels should be added to the stack. Add to the stack pixels that colide with the highest pixel of the stack

DetectColision should return:

1. pixels that should be added to the stack
2. pixels that ahould be set as a brick in state

1 2 | 3 4 5 6 7 8 9 |

End of game:
Number of pixels that didn't sucessfully colide is equal to the length of brick.
