How do you make a flappy bird game can I have some code help

There are various tutorials on YouTube, so i'd recommend searching for one. You can always also check already existing Flappy Bird games here on Scratch!

Look at some tutorials! They’re basically everywhere.
Just look it up on google/YouTube.

Here’s the first video I found when searching on google:

you can use some code like this to get the bird to work:

when green flag clicked
forever
if <mouse down?> then
change y by (10)
end
change y by (-10)
end
when green flag clicked
forever
if <touching [sprite1 v] ?> then
stop [all v]
end
end

Then for the pipes you can use

when green flag clicked
forever
repeat until <touching [edge v] ?>
go to x: (-200) y: (0)
change x by (-10)
end
end

You could program a velocity system for the bird if you know how instead of the more simple approach given

You can get an idea from the code in my project https://scratch.mit.edu/projects/1000104964

when green flag clicked
forever
change [yV v] by [-1]
change y by (yV)
end

when green flag clicked
forever
if <key [space v] pressed?> then
set [yV v] to [5]
wait until <not <key [space v] pressed?>>
end
end

wait until <not <key [space v] pressed?>>
end
end

And for the pipes:

when green flag clicked
go to x: (240) y: (0)
forever
wait (pick random (3) to (10)) secs
create clone of [myself v]
end

when I start as a clone
glide (5) secs to x: (-240) y: (0)
delete this clone

Just put this code on the bird sprite:

when green flag clicked
forever
if <not <<key [whichever key] pressed?>>> then 
repeat until <(vertical velocity) = [0]>
change [ vertical velocity] by [-1]
end

  

else
set [ vertical velocity] to [5]
end
end

you can increase the vertical velocity value in the else branch to increase the speed of falling. Also you can rearrange the code so as to omit the “not” operator if u want.

follow this code by:

when green flag clicked
forever
change y by (vertical velocity)
end

then go to the obstacle sprite and you can make some clones scripts for the obstacles and if then clone touching bird, broadcast death, game over.

The mouse down script could be abused and players could just hold onto the mouse button instead of clicking in an order, also changing Y this drastically will make way for some choppy movements.

Bird code -

when green flag clicked
set [gravity v] to [0]
set [canI v] to [1]
forever
change y by (gravity)
change [gravity v] by (-1)
if <touching [obs v] ?> then
set [gravity v] to [-10]
set [canI v] to [0]
end
if <touching [edge v] ?> then
set [canI v] to [0]
end
end

when [ space v] key pressed
if <(canI) = [1]> then
set [gravity v] to [10]
wait (.1) secs
end

obs-

when green flag clicked
set [score v] to [0]
if <(canI) = [1]> then
set [y v] to (pick random (80) to (-80))
go to x: (290) y: ((y))
glide (1) secs to x: (-290) y: ((y))
if <not <(canI) = [0]>> then
change [score v] by (1)
end
end

That's why I made sure to do it this way (I am not @OsomKoolGuy):

in your bird sprite {coding}:

when green flag clicked
forever
change y by (-5)
if <touching color [{of bottom layer, what ever colour it is}] ?> then
switch backdrop to [your game over screen]
broadcast [your choice]
hide
end
if <key [up arrow] pressed?> then
change y by (5)
end
if <touching [your choice of obstacle] ?> then
switch backdrop to [your game over screen]
broadcast [your choice]
end

when green flag clicked
forever
next costume
wait (1) secs
end

when green flag clicked
go to x: (-132) y: (20)


when I receive [a different one of your choice]
forever
change y by (-5)
if <touching color [{of bottom layer, what ever colour it is}] ?> then
switch backdrop to [your game over screen]
broadcast [your choice]
hide
end
if <key [up arrow] pressed?> then
change y by (5)
end
if <touching [your choice of obstacle] ?> then
switch backdrop to [your game over screen]
broadcast [your choice]
end

obstacle coding {not bird}:


when green flag clicked
go to x: (195) y: (20)
forever
change x by (-3)
wait (0.2) secs
end

when I receive [your choice]
hide

stage\backdrop

when green flag clicked
switch backdrop to [your game on]

when I receive [your choice]
switch backdrop to [your game over one]
wait (5) secs
broadcast [a different your choice]
switch backdrop to [your game on one]
