Just make a variable that keeps track of how long you've been in the air. Basically check if you're at rest, if so, set that timer to 0, otherwise increase it by 1 every frame. If it reaches a certain amount, when you check if you're about to reset it to 0, also check if it got to that amount. If so, subtract "hearts" based on that amount. I can't say more without knowing your movement code, but that is simple enough that you can probably figure the exact code on your own.

Or even easier, in a collision event with your floor object check the vspeed, if it's greater than the safe speed remove hearts.

Example, removes 1 heart for every 5 over the safe speed.
`if (vspeed > safe_speed) hearts -= ceil((vspeed - safe_speed) / 5);`

Actually on second thought, only his code would work anyways, as if you jumped on a trampoline an bounced really high, e.g., my code would fail.

nah, yours would work too .. just check for how long in air with positive vspeed
`counter += vspeed>0`

I don't understand were i put the code??

In your solid block floor thing's collision event (where you put the code that happens when the character comes in contact with the ground). Most likely placed after the code that is already there but maybe still within the outer brackets? You might want to experiment a bit with it to get the desired result.

this is how minecraft deals with it:

when your on the ground. Last_On = Z (or Y)
then next time you land. check if Now_On < Last_On. then check if the gap is big enough to deal damage.

language means nothing.

i have not much coding experience with platformers, but in theory, your using place_meet or a function like that to see if the player lands on the ground.
lets just for example the below code (the place_meat is basicly, this is a example extending your gravity stop code)

if( place_meet(x,y-16) = true)
{//this is start of block
gravity = 0; //stop gravity
dif = last_y - y; //different in levels
if last_y > y and dif > 32 //if the last gound usage is BELOW (meaning a fall) AND difference is enough to take damage (32 pixels)
{//start of block
health -= (dif-32)/32; //every 32 pixels = 1 health damage, tinker with values to check it. 32 pixels is a safe non-hurt
}
last_y = y; //now set our ground_level
}

}

Im guessing you put this in step event and by the way place_meet is an unknown code it dose to work with game maker

sorry, i was under the assumption you knew what your current code does. You DO have a working gravity system in your platform game, correct?
