How do I do a collision to be dead by an enemy in the run tutorial

I have been doing this for hours, and nothing worked. does anyone how to do that. please help me :(

here is the game that is based on the run tutorial and I added a monster, and I am trying to give a collision for the player, does any one know how? https://microstudio.io/i/Tiberius/babyhollowrun/

collide_AABB = function(r1,r2)
return r1.x - r1.width/2 < r2.x + r2.width/2 and
        r1.x + r1.width/2 > r2.x - r2.width/2 and
        r1.y- r1.height/2 < r2.y + r2.height/2 and
        r1.y+ r1.height/2 > r2.y - r2.height/2
end

MicroScript has a cool feature called screen.setTranslation . Try using it - it will make writing a game easier. Try to organize your code into classes and objects.

WOW! thank you. :)

but there is a problem, my character is infinitely jumps if you press the buttons to jump, can you fix please.

New code at top.

Oh ever mind, thank you for fixing it. you man. :)

I am sorry to say but you have made some more problems, the score does not show when you pass the enemy or the spikes. And the speed does not change when pass, and it starts too slow. I am sorry, I know you are trying your very best. :) I hope I can cheer you up.

Please, I love this game. 🥺💔💔

Code changed.

THANK YOU, THANK YOU!!! Loginus, thank you doing this, I hope It was okay for you to do this. :)

You rock, you have teached me many things. And made my first game even cooler and better, I wish I could return the favor, just tell me if you want to. 😎
