Scratch

Hi, Zippzom.

Things are not always exactly the same on the website, but they are supposed to be close. However, they might be a bug in the Java player. I can investigate.

What project is giving you trouble?

should appear red

Hi, Zippzom.

Thanks for reporting this. It appears to be a definite bug/difference in the image filter behavior between Scratch and the Java player on the website. It's a fairly unusual case--to start with black (no color) crank up the brightness so that it looks like it has a color and then shift that color. You can probably work around this by starting with colored circle. You can make it look black by setting the brightness to -100, but it will have a definite color. I have not tried this, but I think it should give the same color in both Scratch and the Java player on the website.

I will look into the Java bug. Thanks again!

This link doesn't work now.

well, heres one that doesn't work for me
http://scratch.mit.edu/projects/Draakx/70250

When offline, there is a colour scale of 0 to 200
With a red sprite, different color effect values will give these colours:
Red=0, Yellow=33, Green=67, Cyan=100, Blue=133, Magenta=167.

When on Java (online), there is a colour scale of 0 to 360
With a red sprite, different color effect values will give these colours:
Red=0, Yellow=60, Green=120, Cyan=180, Blue=240, Magenta=300.

In Axeblade's walking animation, when offline, the fast man is blue, which is colour 130/200.
When online, the fast man is green, which is colour 130/360.

To test whether you are online of offline, see the web mode detection tutorial at http://scratch.mit.edu/projects/1tchy/92324 for instructions.

Then use the   <{ on web?   }>  [/blocks] variable to test: 0=offline 1=on web.

If you are online, you should multiply all colour effects by 1.8.


Instructions:

Step 1.  First, create a small red dot called Sprite1



Step 2.  Add the following scripts to Sprite1:
[blocks]

<when green flag clicked>
<set[ color ]effect to( 133[/blocks]

Step 3.  Create a dot that is the the same colour as the background (It should be the same size and shape as Sprite1).

Then make a global variable called "on web?"
Make sure that you select 'for all sprites

Step 4.
Click the green flag

Then add the following script:
[blocks]

<when green flag clicked>
<wait( 0 )secs>

<forever>
<if><touching color[  colour of Sprite1
<set{ on web }to( 0
<else>
<set{ on web }to( 1
<end>
<end>
[/blocks]

Finally,  move Sprite2 to Sprite1

If you are online, Sprite1 will be green
If you are offline, Sprite1 will be blue

Did you know:

If you are offline, there is a colour scale of 200
On the website, there is a colour scale of 360 colours
This applies to colour effects but not to pen colours.

If you are online, multiply all colour effects by 1.8
