This is a very reasonable script to make a sprite only jump when touching ground and i dont know why it doesnt work. So here it is :

variable

(in air?)

when green flag clicked
forever
if <touching [platform v] ?>then 
set [(in air? v] to [no]

else

set [(in air? v] to [yes]

end

if <[in air?] = [no]> then
if <key [up arrow v] pressed?> then
set [gravity v] to [15]

end
end
end

DOESNT WORK

With the gravity set block, also use

change y by (10)

Wait set gravity to 15 is the same tho

It is for gravity to work

It doesn't work because the “Gravity” custom blocks moves you up until you don't touch the ground and then when you check collision after that are you above air it will always be “yes”.
So remove your check collision part , and instead set the “in air” to either yes or no at the gravity custom block.

Wdym? Show me the code.

And i removed the

if <> then 

  

else

end

block and in the gravity custom block i added the ‘in air’ code.

DISCUSSION CLOSED, THANKS GUYS FOR THE INFO, THE BUG IS GONE SO PLEASE DONT POST ANYMORE
