What is it you are trying to achieve?
Well. I am new to Turing.
I am taking a Grade 10 course on it.
I have just came across one little small thing.
It may seem stupid to you higher people.
But here it is.
I need to know how to set a max high to jump, and I would also like to know how to add Borders so my sprite cannot go off screen on the x axis.

Help would be appreciated. Thank you. Smile

below is the concept of what to do and how it works. read it carefully.
code:

if keys (KEY_LEFT_ARROW) then
    x := x - 10 %% 10 being speed (put it as a variable speed)
    if x <= 0 then %%if players x location is (off the map or at 0 of map)
        x := 1 %%put him on the map so he can't run off it
    end if
   
    if walkingLeft then %%your basic set up for changing pictures
        draw walkingLeft
    elsif walkingRight then
        draw walkingRight
    else
        draw standing
    end if
end if
%%same idea for right X axis,
%%set him back on the map if he goes to run off, before he's drawn
%%And again, same with his JUMP Height, Except this uses "Y" Axis.

If what the OP means is making it so you cannot jump infinitely, then just think of it like real life. What is the biggest condition required for jumping? It is having something to jump off of. You can tell when the person (or w/e your picture is) is on the ground by when it is able to fall. Use a boolean value to only allow the person to jump when it is on the ground.

Thank you everybody. But I figured it out on my own Smile

But I did take your border idea Token.
Thanks.
