Movement oddity...
by Blake 15 Mar '06

15 Mar '06

Hello, again: I've found an oddity with a simple script. I've attached a JPG of the script, which is the only one I've created in the image. Basically, the object is to track the mouse. If its X/Y is not equal to the mouse's X/Y it changes its own X/Y by one. If I set the script to fire an even number of times per second, it works. If I set it to fire an odd number of times, it bobbles. It goes to the right place, then moves off it by one, then goes to the right place. As if the update of the X/Y occurs out of synch with the event firing. ? ===Blake===

Testing for clicks.
by Blake 15 Mar '06

15 Mar '06

Hey, Squeaklanders, My son is trying to set up a game that follows certain RTS (real-time strategy) conventions. In particular, he wants the user to be able to left-click on a unit and then right click on a place in the world where the user is supposed to go. This, of course, requires being able to test where the user is clicking, and distinguishing from right and left clicks. Doable? ===Blake===

Some hints, that might be responsible for your problems: 1. You should install Squeak as an Administrator 2. Squeak itself should be installed in directory C:\Program Files\Squeak (or something like that since each language names its directories different) 3. Can you see a directory C:\My Squeak? Beyond this directory thers should be a directory like 'Your name', e.g. C:\My Squeak\My name There Squeak tries to store its 'projects'. There you need to have all sufficient 'rights', for example 'write a file'. Ask any person who can change the rights. Additionally tell us which squeak version you have. You can choose the language in the 'Navigateur' when you click on the 'earth'-Symbol. You can see the version by pressing 'Esc' then clicking on 'help' and then in the help menu on 'about this system'. There you should have '3.8-05'. Also the 'latest update:' information is important. My current version is #531, there might be a more recent update. An error message might be irrelevant. What does it say?

Re: [Squeakland] Squeak at the NASA :)

I just tried it with Firefox. After the updates I get an empty squeak screen, flaps all there but no nasa stuff. Second time (sundial project) I got a strange pixeled splash window, firefox hang also. After restarting firefox, everything was ok.

Re: [Squeakland] dot
by Arvind Grover 08 Mar '06

dot is just a placeholder. you want to replace it with something much more interesting. i.e. i have two objects, a mouse and a plate with cheese on it. i have a test that says: TEST mouse overlaps cheeseplate YES cheeseplate look like emptyplate (used to say "look like dot") NO from the emptyplate's handles, i click on the brown, rectangle one which gives me a tile that i can put over top of "dot" make sense? -----Original Message----- From: squeakland-bounces(a)squeakland.org on behalf of Sholom Eisenstat Sent: Tue 3/7/2006 7:02 PM To: squeakland(a)squeakland.org Cc: Subject: [Squeakland] dot Dots Can someone please explain 'dot'? What's the theory of 'dot'? How can we change the position of 'dot' so that 'move toward dot' is not movement toward top left of world? Sholom Eisenstat

collisions, heading, theta
by Sholom Eisenstat 08 Mar '06

08 Mar '06

There's a game in development; the best analogy would be something with pucks on a tabletop. Fiza is developing scripting so that one object, moved by a mousedown, when it hits another object, will impart movement at the angle of the hit. Are we on the right track thinking that she should be able to use heading and/or theta and/or heading theta to transfer the angle/direction of the moving puck the the puck it hits? Sholom Eisenstat

Newbee question: What am I doing wrong?
by Paul McMahon 07 Mar '06

07 Mar '06

Hi There, New to squeak. Trying to evaluate this for use with a group of elementary aged students in Hong Kong. Problem is, every time I download a project it does not seem to run like it is supposed to. For example, just downloaded a skateboarder from http://schools.tdsb.on.ca/donmillsmiddle/cyberarts_dmms/squeak Clicked the timer on the script and it does not go anywhere. Same thing happens with all of the etoys that I have downloaded on the http://www.squeakland.org/ Kidsplay etoys page. What am I doing wrong? Do I have to do something to these to get them to work properly? Thanks Paul

Re: [Squeakland] Copy an object programmatically.
by Randy Heiland 07 Mar '06

The key is that you can create a variable which is of type 'Player' (on the variable's menu, select 'change value type' and choose 'Player'). E.g., I created a player variable called 'clone1' for my sketch (actually I called it 'clone', but apparently it conflicted with some reserved var, so a '1' was appended). You can then 1) assign something to that var - e.g. 'sketch's copy', and 2) use that var on the left-hand of an assignment - e.g. replace the 'sketch' in 'sketch's x <- <value>' with 'sketch's clone' Hopefully the attached image will help clarify. You might also want to get in the habit of doing things in a playfield instead of in the world. Please copy the list if you still have problems. --Randy > -----Original Message----- > From: Blake [mailto:blake@kingdomrpg.com] > Sent: Monday, March 06, 2006 5:26 AM > To: Randy Heiland > Subject: Re: [Squeakland] Copy an object programmatically. > > On Fri, 03 Mar 2006 03:56:35 -0800, Randy Heiland <heiland(a)indiana.edu> > wrote: > > > Your question gets into the semantics of a 'copy' vs a 'sibling', but... > > Well, I think I understand that. > > > short answer: > > http://squeakland.org/pipermail/squeakland/2005-August/002707.html > > Thanks. > > I think what threw me is that it's called "ship's copy", which doesn't > seem like an action. > > OK, so I make a copy and put it into the world with > > word include:ship's copy > > so how do I get a variable of ship's copy that I can set the starting > location in the world?
