Subject: Re: The bouncing sound

Scott,

Here's a project file that demonstrates the problem. I'm working in the most recent ver. of Squeak from www.squeak.org (just downloaded a few days ago) .... 3.9-final-7067

When I activate the script with the object controlled by a joystick, the first few times it hits the top of the world and it's silent - all is well. But at some point, after 3 or 4 or 5 collisions, it's no longer silent.

All help much appreciated and thanks very much in advance for looking at the project (made by a student in the class I'm teaching).

Ab,

Mark

Hi, polishookm,

I cannot reproduce the phenomenon you describe in any image I have close to hand -- not in Squeak 3.9, not in Squeakland3.8-05, and not in the OLPC etoys image. (Can anyone else?)

What version of Squeak are you using? If it's 3.10, I'll leave it for other 3.10 users to track this down, since I don't have a copy of 3.10 handy.

Otherwise, perhaps you could email me a copy of a project of yours which exhibits this symptom...


Cheers,

-- Scott

I"m finding that with

[Rectangle forward by 5]
[Rectangle bounce silence]

the rectangle eventually collides with the top of the world and bounces off in the opposite direction - with no sound ... the bounce is silent.

However, this script

[Rectangle forward by JoyStick's upDown * 8]
[Rectangle bounce silence]

doesn't allow the Rectangle bounce silently off the edge of the world. In this case, when the rectangle reaches the top of the world, it makes a bouncing sound. The exact sound can be selected in the [Rectangle bounce silence] tile. But selecting 'silence' as the sound doesn't seem to work.

Am I missing something obvious? Shouldn't it be possible to silence the bounce?
