But I can't find any continuation. Did you finish this project (and where might I find more details), or is this all the further you took this one?<br /><br />Thanks!Ravenhttps://www.blogger.com/profile/10434437834457303196noreply@blogger.comtag:blogger.com,1999:blog-29868932.post-81109879170875677532007-11-05T20:49:00.000+10:302007-11-05T20:49:00.000+10:30Hi Bill,I like your blog very much, thanks for wri...Hi Bill,<BR/><BR/>I like your blog very much, thanks for writing it.<BR/>You might be interested in Peter's and mine implementation of Space Invaders with Etoys you can find on:<BR/>http://www.squeakland.org/project.jsp?http://www.emergent.de/pub/smalltalk/squeak/projects/petersInvaders.003.pr<BR/><BR/>It dates back to the time there was no keyboard support in etoys so you have to use the mouse and click on the arrows to move the ship and on the square to shoot.<BR/><BR/>You might also want to have a look at <BR/>http://www.iam.unibe.ch/~scg/Archive/Papers/Gael06aC5.pdf<BR/><BR/>Cheers,<BR/><BR/>MarkusAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-29868932.post-43555952535689421762007-11-03T02:07:00.000+10:302007-11-03T02:07:00.000+10:30Comment from Dreyfuss Pierre-André at the squeakl...<A HREF="http://squeakland.org/pipermail/squeakland/2007-November/003923.html" REL="nofollow">Comment </A> from Dreyfuss Pierre-André at the squeakland list:<BR/><BR/>"Nice, You have found the rule that with Etoys we have to see What an object knows and can do for itself to put the scripts in the right objects. So the bullet knows when it reaches the barrier and can delete itself.<BR/><BR/>I found about the same solution trying to solve this project.<BR/><BR/>To let the gun move in the same direction after shooting, I have tested the heading value. If it is -90 I put @lt;left@gt; in the input buffer, if it is 90 I put @lt;right@gt;<BR/><BR/>With the test on the key pressed, I have added to set heading to 0 if the @lt;down@gt; is pressed, This will enable to put @lt;down@gt; again after shooting if heading is 0. This way the gun remains still if the down key was pressed before shooting and go no moving to right or left."Bill Kerrhttps://www.blogger.com/profile/00206808014093631762noreply@blogger.com
