i made it so that health went down by -1 when touching boss and theres a total of 3 health. but the health rapidly goes down so that you lose all 3 health by colliding with the boss once. I want to make it so that the player is invincible for a second so they can get away

If that's the only source of damage, you could just add a wait 1 second to the end of the code for losing health.

If there are other sources, you can use a variable - let's call it Invulnerable - then get your damage code to check it's No before you apply the damage, and then to set Invulnerable to Yes.

Elsewhere (probably in your player or health sprite), put in:

forever
if <[Invulnerable] = [Yes]> then
wait (1) secs
set [Invulnerable v] to [No]
end
end

I think that should do the trick.

I´ve seen some games where when the player receives damage it moves some steps back and the enemy freezes by one or two seconds.

Knockback is also a good idea.
