Hello Stef,

I played with the breakout and the ball starting speed and direction is a bit too much unpredictable. :)

unfortunately the speed of the game which is needed for the XO is too fast for ordinary computers. Try the sar-file - in this version the velocity of the ball is reduced.

May be changing the sokoban icons would help because the holes are not hat clear to me.

Right, they are not that obvious. But try the new Sokobaenban. The graphics are much better.

Best, Robert

Hello --

I am glad to announce the availability of a new Squeak Project! The game is called BlockAttack and can be downloaded from http://www.swa.hpi.uni-potsdam.de/projects/olpc/ .

Have Fun! Robert

Dear all --

We released a new student project today. It is a implementation of the game Pipes - nice graphics, really addicting and a lot of fun to play :-) It can be downloaded from http://www.swa.hpi.uni-potsdam.de/projects/olpc/. http://www.swa.hpi.uni-potsdam.de/projects/olpc/

Have Fun!

Hi, Robert

Thanks for all the nice games you guys produce. Pipes works nice on my windows machine, I'll have to test it on the XO, too.

BlockAttack do not work on my windows machine. It seems to have some issues with path names to image files with forward and backward slashes.

Fixed.

Thanks again, Robert

Hi, Robert (and Robert),

I'm interested in speeding up the project loading for that kind of projects as well, which mostly consist of Smalltalk code for new classes and not much Etoys objects. Your games are this kind.

Currently, the standard way to include Smalltalk changes is to have change set in the project and have it compiled by standard Smalltalk compiler upon loading. However, you can actually include CompiledMethods in a project and load them quicker than compiling. My experiment is along this line.

I made a proof of concept tool for it. To try it:

- File in the attached change set into a relatively new image.

- Load one of your games (such as Pipe) into the image.

- Go to the project and *clear* the changeset of the project from ChangeSorter.

- Evaluate "ProjectPackager new open" somewhere. You'll get a small window that is titled "Packager".

- In the upper pane of the Packager, type something like:

#(PlAbstractField PlAbstractFieldTest PlAdjacentBendPipeTest PlAdjacentCrossPipeTest PlAdjacentEndPipeTest PlAdjacentStartPipeTest PlAdjacentStopPipeTest PlAdjacentStraightPipeTest PlAdjacentTPipeTest PlBendPipe PlButtonMorph PlCrossPipe PlEasyPolicy PlEasyPolicyTest PlEmptyField PlEndPipe PlFieldMorph PlFieldMorphDragAndDropTest PlFieldMorphInitializationTest PlFileResourceManager PlFileResourceManagerTest PlFillingNotification PlFillingStrategy PlFloodingNotification PlGame PlGameMorph PlGameOverState PlGameState PlGameStateTest PlGameTest PlHardPolicy PlHardPolicyTest PlHighscoreMorph PlImageMorph PlInitState PlIntegrationTest PlMediumPolicy PlMediumPolicyTest PlMemoryResourceManager PlMenuMorph PlMockGame PlMockLevelPolicy PlMockPolicy PlPausedState PlPipe PlPipeSimpleFillingTest PlPipeSlowFillingTest PlPipeSupply PlPipeSupplyMorph PlPipeSupplyMorphTest PlPipeSupplyTest PlPlayfield PlPlayfieldMorph PlPlayfieldTest PlPresentationPolicy PlRandomizingDecorator PlResourc eManager PlResourceManagerDecorator PlRulePolicy PlSARCreator PlScoreCounter PlScoreDisplayMorph PlScoreDisplayTest PlSimpleFillingStrategy PlSlowFillingStrategy PlStartedState PlStartPipe PlStopPipe PlStraightPipe PlThemingDecorator PlTimeLabelMorph PlTPipe PlWaterFlowState PlZipResourceManager)

and accept it. You'll see the list of classes. (You could enter an expression like:

[:c | c name beginsWith: 'Pl']

but it would include other classes like PluggableTextMorph and wouldn't quite do it for this.) Also, you could probably remove all the Tests from the list above.

- Set the name of project from the ChangeSorter or the oval text in the Sugar Bar.

- Now, press the "Save" button in the Packager. It will create a project with CompiledMethods.

- Compare the performance of project loading; Pipe didn't give as much boost as I saw other instances, but it speeds up it a little bit.

It is *experimental* and it may as well turn out to be a bad idea. But if you are interested in making loading these games faster, please give it a try.
