Scratch

This is for the person who asked me how to use sensor blocks.

I have a Mac, tell me if you have windows.

To make a sensor block work, make sure you have already done these things first-

1. Make sure mesh is enabled, read this tutorial-

http://scratch.mit.edu/projects/MathWizz/849173

2. Download Scratch 1.4 twice saving the folders you download in different names. The reason why you do this is so you can open two Scratch windows at the same time, one from each folder, One scratch program doesn't allow you to open two windows from it. You need two scratch windows to program mesh games.( Note- By two windows I don't mean operating systems) This is what my scratch folders look like:



3. To start making the project in which you
want to use the sensor block for, Open both scratch programs and have two windows side by side to use like this:



After you are sure you have done those things, to use the sensor block:

Connect the two windows, press shift + left click with the mouse on the share button next to edit, and it should say host or share mesh. Click Host Mesh, it will pop up with an ip adress which is yours, don't click ok. If you did press shift + left click with the mouse on the share button next to edit and click show ip adress. Go to the other window and press shift + left click with the mouse on the share button next to edit, click on join. It will ask for your ip adress, type in the ip adress from the other scratch window, put all the .'s and don't type anything wrong. You have now connected them. using this same way you can play the mesh game when you have completed the project.

Test it out, make one variable on window 1. unfortunately this picture doesn't show.



Go to window two, drag one sensor block to your script area.
Click on the black triangle to open up a list:



This is the list with out the variable:



The variable you made on window one will be shown at the bottom of the sensor block's list on window two like this one, in this case the variable is game.


That is how to use sensor values! Tell me if it works, if not I will give further instructions.

You can use broadcast and recieve instead of sensor values or both too.

If you have mesh set up this is the information you need:

This tutorial tells you the basics of making a multiplayer game, if you still want more i will tell you-

Tutorial- http://scratch.mit.edu/projects/martianshark/713175

These are several Multiplayer games I made-

1.Tug of War- Player one taps l key, Player two on another computer taps l key

       Person 2: http://scratch.mit.edu/projects/itsmomito/859455
Status- Available for download

2. Chat Box- Chat with each other across your network

       Person 2: http://scratch.mit.edu/projects/itsmomito/854494
Status-Availble for download

3. Mesh Race- realistic simulation of racing with two people
Link- Person 1: http://scratch.mit.edu/projects/itsmomito/854493
       Person 2:http://scratch.mit.edu/projects/itsmomito/864537
Status- Beta Stage- much slower online.

Note- When making multiplayer games you should have two separate projects, one for each person who is playing.

Sorry, i wrote that on accident, yes I know you can only connect with people in your network.
