Scratch

I found a bug related to the upper/lowercase behaviour of scratch in flash player (to be honest it is kinda wonky in 1.4 to begin with).

The project in which you can see the bug: http://scratch.mit.edu/projects/molkemon/3138922

In this project I made a simple ASCII-char to binary number converter. The first problem is that if you compare the "answer" block to a given value, scratch does not care about case. if answer = a and if answer = A are the same to scratch.

There is a workaround to that though. If you define a list with lets say all the lowercase characters and then check if the answer block is part of that list, it will check correctly and return true or false depending if the answer given was in fact lowercase or not. More info on this workaround can be found on your own wiki: http://wiki.scratch.mit.edu/wiki/Case_Sensing  --> using lists

I have implemented this workaround in the above linked project and it does work offline with 1.4 AND with the java player. However, it does NOT work with the flash player. In flash it seems the "contains answer" check versus the list always returns true, even when the character is not lower case.

How to reproduce the bug: Open my project offline or with the java player. Input first a and then A as answers. You will see the results will be different (and correct). Now switch to flashplayer, again enter a and A. The results will be the same this time and therefore in case of the upper case A, wrong.

doesn't work block "if on edge, bounce" exactly as it is in the Scratch

(in scratch, ball does not bounces around the screen)

You're better off going to help with scripts. If this is an website problem stay here!

Ghost not working

http://scratch.mit.edu/projects/ethurber/3146466

repeat until <(costume #) = (costumeCount)>
     set [ghost] effect to ((costume #) * (-7))
     next costume
end

This project uses three sprites to explore polygons in different ways. The user selects a 'pen' sprite using a slider (1..3) to pick which demo to show; the green flag script then broadcasts a message to the appropriate sprite.

Each demonstration shows different variables on the stage, and there is a 'hide variables' broadcast so that each sprite hides its variables before the next demo begins.

I have two problems with the Flash viewer:

1. The 'show variable' blocks do not retain the positions that they were given at design time with the result that the variable display obscures the polygons drawn by the sprite.

2. The 'pen2' sprite use a slider called 'angle to turn'; this allows the user to explore different drawing effects. After uploading the project and selecting pen=2, the 'angle to turn' value is no longer a slider.

My project no longer works.  It gets stuck sensing Turbo Mode.

It used to be very reliable, but something's changed in the Flash player and now it no longer can sense when the player starts Turbo Mode.

EDIT:

After a little testing, the following block

wait (0) secs

takes significantly longer in turbo mode than it used to take.

In a loop of 100 times, it now takes just over 3 seconds where it used to complete in less than a second.  It is now running in the same amount of time as non-turbo mode.

Ghost effect needs to be a positive number.

NVM - my fault 

In Robot man {Now for non-professionals}, I Got an Idea from a friend, opened in scratch, made some changes, But when I submitted it, Some words didn't Show up.


I am using Internet Explorer

My project sound is too slow and I know its a Glitch! sad

On the game (The hover king) once you beat the 2nd level it doesn't switch to the next costume like it's supposed to do. It works fine on scratch, but doesn't work online. ???

NON mi appare la finestra.
