is _view.trailSet.newSegment(); working for array set? February 10, 2015 10:53AM UTC
lookang 245 Posts	dear prof paco, i managed to get is _view.trail.newSegment(); to work for a single line which is wonderful. thanks! but array of lines work with the line of code too? is _view.trailSet.newSegment(); // working for array set? see my scr for details on the initialize button! i commented out the line to ensure the model runs, enabling it will hang the model more info can be found here http://weelookang.blogspot.sg/2015/02/ejss-2-cannon-aim-at-each-other.html Post edited February 10, 2015 at 10:54 AM EST.

Francisco Esquembre 237 Posts	Dear LooKang, The newSegment() function works for trail sets too, but on an individual basis. Hecnce, you must provide the index of the rail in the set for which you want a new segment. As in: _view.trailSet.newSegment(0); // New segment in the first trail of the set Of course, a for loop can be used to create a new segment in all the trails of the set.

Dear Prof Paco,

it looks logical but i could not get it to work with one or both lines.

in my init button the actions to take are
// _view.trailSet.newSegment(0);
//_view.trailSet.newSegment(1);
memorycolor=memorycolor+1;
t=0;
x[0] = xs0;
y[0] =ys0;
x[1] = xs1;
y[1] =ys1;
vx[0] = vxs[0];
vy[0] =vys[0];
vx[1] = vxs[1];
vy[1] =vys[1];
_initialize();

when i un-comment out the first 2 lines or a single line would freeze the simulation after i click on the button that has this line active.

i am using EJS_5.1_150125, is there a newer release?

Francisco Esquembre 237 Posts	Dear Loo Kang, You found a bug in the code! I have fixed it. You need the new EjsS at http://fem.um.es/EjsWiki/uploads/Download/EJS_5.1_150210.zip This one will run your code ok. This is an experimental EjsS where we have done some internal changes. If you find any other bug, please let me know. Best regards, Paco Login to reply \| Condense

Francisco Esquembre 237 Posts	Hi Loo Kang, I'd need to source code for this simulation to see what happened. You can attach it here or email it to me at fem@um.es Best, Paco Login to reply \| Condense

Try this
https://www.dropbox.com/s/5dtz6iahw4v9l06/ejss_src_SHM04.zip?dl=0

In addition.
The other bug I notice
1 trail that t>0 active seems to experience I bigger gap than t>0.
2 the CSS used to make invisible the panel is not working as previous versions of ejss was able to do.

Thanks!

Francisco Esquembre 237 Posts	Dear Loo Kang, It seems to me that the release you used for this model has some bug that we fixed recently. Please, use this release of EjsS (or later, if public) and recompile the model. http://fem.um.es/EjsWiki/uploads/Download/EJS_5.1_150222.zip Paco Login to reply \| Condense

dear prof,

thank for the new link to EJSS.

i compile some files and found a bug

the line
_view.plottingPanel.setProperty("CSS",{ "display" : "none" });
which i used a checkbox to action on and off,
it used to work in EJS_5.1_141205
but not for EJS_5.1_150125, EJS_5.1_150210(with the error of the right panel solved already), EJS_5.1_150222.

hope it can help in your newer releases of the cool EJSS tool :)

Francisco Esquembre 237 Posts	Dear Loo Kang, Please, send me the SRC file for this example and I'll see why it does not work. Paco Login to reply \| Condense

Francisco Esquembre 237 Posts	Hi, I tried the example with my latest EjsS at http://fem.um.es/EjsWiki/uploads/Download/EJS_5.1_150302.zip and it works ok. (While the Full screen link to your dropbox doesn't.) So, I think we somehow fixed this problem. Please, try the latest EjsS. It is not yet public, but it will be soon. Paco Login to reply \| Condense
