Collision with the ground

Dylanica

I am making a game which is like minecraft but i have a problem. To make the character collide with the blocks i did something like this:

when green flag clicked
forever
    
if <not <touching [ Ground] ?>> then
    
change y by (5)
end

end

But this doesn't work very well because you can walk into the block and just hang there inside the block
Does anyone have advice?

when I receive [Cookies v]
repeat until <(Cookies) = [ 0]>
play sound [Happy Noises v]
change [Cookies v] by (-1)
    
end

oops i meant

change y by (-5)

when I receive [Cookies v]
repeat until <(Cookies) = [ 0]>
play sound [Happy Noises v]
change [Cookies v] by (-1)
    
end

is anyone going to reply?

I can help:

when green flag clicked
set [gravity v] to [-0.3]
set [velocity v] to [0]
set [bounce count v] to [0]
forever
    if <touching color [(ground color)] ?> then
    
if <(bounce count) < [2]> then
    set [velocity v] to ((velocity) * (1)
set y to ((y position) + (velocity)
set [velocity v] to ((velocity) / (5)
set y to ((y position) + (velocity)
change [bounce count v] by [1]
else
set [velocity v] to [0]
end
else
set [veloctiy v] to ((velocity) + (gravity))
set y to ((y position) + (velocity))
end
end

Thank you but you misunderstood my question
I meant that you can't fall through the ground you can walk straight through walls

when I receive [Cookies v]
repeat until <(Cookies) = [ 0]>
play sound [Happy Noises v]
change [Cookies v] by (-1)

You need to correct for both x and y collisions, ideally resolving one before the other takes place. Try something like this:

when gf clicked
forever
if<key [right arrow v] pressed?>
change x by (5)
if<touching [floor or wall v]?>
change x by (-5)
end
end
if<key [left arrow v] pressed?>
change x by (-5)
if<touching [floor or wall v]?>
change x by (5)
end
end
change y by (-5)
if<touching [floor or wall v]?>
change y by (5)
end

If you want more jumping, more realistic gravity, etc. let me know

WOW thanks so much i can't believe it was so lol. And no thank you i have already figured out how to make realistic gravity: http://scratch.mit.edu/projects/25561779/

repeat until <(Cookies) = [ 0]>
play sound [Happy Noises v]
change [Cookies v] by (-1)

I´m just saying how to make gravity, do this:
FIRST CREATE A VARIABLE NAMED Y VELOCITY

when green flag clicked
go to x: (-142) y: (-33)
forever
change y by (Y VELOCITY)
set [Y VELOCITY v] to ((Y VELOCITY) * (.8))
if <touching color [#d0d60c] ?> then 
set [Y VELOCITY v] to ((Y VELOCITY) * (-0.8))
  

else
change [Y VELOCITY v] by (-3)

end

when green flag clicked
forever
if <not <touching [ground] ?>> then
repeat until <touching [ground] ?>
change y by (-3)
end
end

end

it is that easy

Don’t necropost, this is old.

sometimes, you just have to change a way of thinking to solve a problem. -griefercube
