When I was developing my Flappy Bird game, there was something strange. Every time I clicked the Green Flag, nothing happened. I tried to use a message broadcast to start it up, but it didn't work. The code went like this:

when green flag clicked
go to x: (0) y: (0)
forever
change y by (-1)
end

when green flag clicked
forever
if <<[-159] > (y position)> or <[139] > (y position)>> then
set [fail v] to [true]
stop [all v]
end
end

No matter how many times I clicked the green flag, nothing happened. The script didn't run.

Can anyone help me with this? Please? It's impacting my game and if the Scratch Team sees this, please fix it!

Well, it is kinda a design bug because Scratch does not make it clear which of the two green hat stacks runs first. If the one with the stop all always runs first and your sprite’s Y position true for that if statement then your project will stop and the stack with “goto x:0 y:0” will never execute.

I try not to remember what the rules are for the order of execution because it’s better to have one green flag that kicks everything off with broadcast statements.

Edit: I wrote a small test case with two sprites that should each do the same thing but one of them has the problem you describe and the other works.

Try this.

when green flag clicked
go to x: (0) y: (0)
forever
change y by (-1)
end

when green flag clicked
wait (0.01) secs
forever
if <<[-159] > (y position)> or <[139] > (y position)>> then
set [fail v] to [true]
stop [all v]
end
end

Make a separate topic to discuss your issue, this thread is old.
