how to make screen effects with low health?

[Rayzero-x]

you know how in some games like resident evil, the last of us, etc, when you take a high amount of damage your life meter is low indicating that you're almost dead there is a red like effect that fades in and out, how to do that?

Do you want to make some blinking effect when HP is low?

You could spawn it in player's pain animation.  Just make a (for example) pain9 animation

Then give enemies attack9

Attacks always do the same damage in openbor, so give attack9 to any move that does high damage.
