hello . can you hep me please this isn't working and I don't know why?

the link is https://scratch.mit.edu/projects/166718966/

1. The character starts touching the police, making them loose lives already
2. In order to make it work, you need to change the stop all script to less then 1 because less then blocks in scratch don't have an and equal to option.
3. I recommend putting a wait 1 second block in the loosing a life script.

You:
(If((variable:lives)=0)then)
(broadcast(game over))
(stop(all))

Scripts section of backdrops:
(when I receive(game over))
(switch backdrop to(Game Over!!!))

The (Game Over!!!) backdrop may be a red screen with white letters that say “Game Over!!!” or whatever you want. And you may want to include a:
(When backdrop switches to(Game Over!!!))
(hide)

in all of your sprites.

I agree ^^^
You can avoid the last part @Saaka suggets hidden sprites by makeing a background as an Sprite for GameOver going to front and a size covering the whole screen.

Try this, I have definitely had trouble with things like this before (This is for the cat):

when green flag clicked
forever
if <key [ right key] pressed?> then
move (10) steps
if <touching [Police man v] ?> then
stop [all v]
end
end
end

Hopefully that helps!
