Is there a simple script for wall detection that won't let the player through a wall? I can't seem to find a good answer to this.

The sensor blocks touching sprite or touching color would be the usual ones to use. Look in the sticky topics if that doesn't make sense..

What physics engine are you using? Can you share the project?

Here's my physics

set the ghost effect of your current sprite to 100, put a colour on each side, we will name the colours 123. 1 - left 2- up 3 - right

In the script I gave you in the other thread it says, if key pressed do this, change it to if key left arrow pressed and colour 1 not touching (wall colour)
repeat for the right.
Now make a slighty (by like 1) smaller identical box and make it go to the hidden one forever.

As for jumping, please reshare your project

Yeah, here's the game

http://scratch.mit.edu/projects/11936990/

Here, it doesn't detect walls yet but everything else is good!

Ok, thanks. Could you take it down now? Since it's nowhere near finished, could you take it down?

ok

i cant find a script block for collision. i did when touching color black then change y by gravity. please help

There isnt any block that checks if a color Isnt touching a color- only

 and<color [#00ff00] is touching [#0000ff] ?>
<touching color [#ff0088] ?>

First, this is a necropost, second, to prove you wrong:

<not <touching color [#ff0088] ?>>

How can I check if my player collides with the flag?

make a new topic for help instead of necroposting, please

You Can use A Sensing Block, And Use It To Say:

when green flag clicked
forever
if <touching [Flag v] ?> then
set [Do Something v] to [Anything]
end
end

See if that helps

is there anything in this chat that is recent?

Please don't necropost

Necroposting is when you post on a topic that has been inactive for a while

When you post on an old topic it puts it back on the first page pushing down newer and more relevant posts

SkORINe, I think this code might help you:

You need to make a variable for gravity called ‘y velocity’
And to simulate gravity acceleration, you can use this code:

when green flag clicked
Gravity - Run Without Screen Refresh

[scratchblocks]
define Gravity
forever
change [y velocity v] by (-1)
if <[y velocity] < [-20]> then
set [y velocity v] to [-20]
end
change y by (y velocity)
if <touching [platform v] ?> then
repeat until <not <touching [platform v] ?>>
change y by (1)
set [y velocity v] to [0]
end
end
end
[/scratchblocks]

For the flag, just say:

when green flag clicked
if <touching [Flag] ?> then
set [Do something] to [Do something]
end

I don't actually mean the variable, I just mean do something
