and thanks for taking the time to look at my question.
I'm still a beginner (relatively, a few months of experience) at programming, and I'm trying to make a simple game in processing. I want to have an eval function so that I can evaluate some typed in strings. This is just a simple game, so security isn't a problem, and I don't mind if certain things that get typed in will create unusable code because the code inputted will only be creating new shapes and not messing with existing code. I tested out the eval function by doing this.
eval("background(0);")
but the background obstinately stays white. Am I doing something wrong? (as I suspect) This is my first time dealing with evals.
Thanks for you help!
I can confirm that the eval("background(0);") approach does not work for Firefox, IE or Chrome. background(0); does work. Maybe you can work around this by taking apart the string and looking at the specific information there. I was able to do this with the followin example:
<!DOCTYPE html>
<html>
<body>
<script src="processing.js"></script>
<script type="application/processing">
size(600,600);
var str = "background(100);";
if (str.indexOf("background")==0){ //does the string start with "background"
str = str.replace( /\D+/g, '');//number extraction found on http://stackoverflow.com/questions/10003683/javascript-get-number-from-string
background((int)str); //use just the number
text(str,10,20);
}
</script><canvas></canvas>
</body>
</html>

I have a grenade BP which the hero throws and wondering how you would set this up ..
I have tried and works fine but this way is caused by a sphere collision and checks what is inside the collision during detonation.
I tried without casting but this didn't work out very well for me, Is there something else I should be doing?
Please ignore the "get overlapping actors" class filter, I only done that as a test, i usually leave it blank.
ideally id like to try some sort on line trace when the bomb detonates so it can check if its a direct hit rather than triggering even when safe behind cover.
Any help is greatly appreciated, thank you!
Is there casting necessary? say I had 10 other different AI characters, id have to cast through them all right

I found out using a MultiSphereTraceByChannel works much better.
I am currently creating a array that holds a bunch of different data. One of the data points is to hold the most recent date accessed. For some reason I can't put year() into the array without the program breaking. Code below.
world_saves.push([[year()]]);
What's the reasoning behind this, and how do I set put the year into the array without a error. I've tried defining year() into a variable, but once again I get a error. Error below.
World_Data.js:5 Uncaught ReferenceError: year is not defined
Thanks in advance!
EDIT:
For anyone viewing this, this is the correct code to use.
var pjs = new Processing();
world_saves.push([[pjs.year()]]);
With the caveat that I've never used processing.js, it appears that you have to instantiate an instance of it first before calling methods on it.
Something like:
var pjs = new Processing();
world_saves.push([[pjs.year()]]);
also note: You do realize you're pushing an array of an array containing the year here, right? (vs. just world_saves.push(pjs.year());)
I see that you already got this sorted out, but just for your information: with Processing.js, typically you'd write Processing code and have Processing.js create the Processing instance and call the setup() and draw() functions for you. There are a ton of ways to do this (many are outline on this page), but the basics would look like this:
<script src="processing-1.3.6.min.js"></script>
<script type="application/processing" data-processing-target="pjs">
int[] worldSaves = new int[1];
void setup() {
size(200, 200);
worldSaves[0] = year();
}
void draw(){
background(0);
text(worldSaves[0], 10, 10);
}
</script>
<canvas id="pjs"> </canvas>
What you came up with isn't really wrong or anything, but I also don't know why you're using Processing.js if you aren't using the Processing part of it. So eventually you might end up with something more like the above.
Example:
.. member:: CK_UTF8CHAR model[16]
Gives me both the type and the name bolded and hyperlink not working.
Practically we are forced to use this cases like that:
.. member:: model
Because otherwise it would be incorrect (use it without array and with the same type).
Well, this seems to be a real bug in Sphinx. I reported that and it was confirmed. I've come up with a little workaround for now, but it's more of a crutch. Just put the following to the layout.html file of your Sphinx theme:
<script>
$('dl.member dt').each(function() {
$(this).find('big:first').text('[')
$(this).find('big:last').text(']')
});
</script>
Now you may use parenthesis instead of brackets in broken structures: model(16) becomes model[16] (and label(\ ) becomes label[], but only within the .. member:: directive.
I know it is not a very elegant solution, but it is OK as a temporary fix, until the bug gets resolved.
I try to draw with libcairo, it draws nothing. I downloaded the diagram sample, it works fine [draw.c], but code example from the site doesn't draw: like http://cairographics.org/samples/fill_and_stroke2/
why?
Thanks!
The code you linked to looks fine. But of course, it's not a complete program. Without seeing what code you've wrapped around the example to make it run, all I can guess is that you may need to call cairo_show_page() and cairo_surface_flush().
I would like to know how to get the value for the +1 value((if there are 10 clicks +1 button, store 10 as a variable). This would be helpful for analysis purposes.
I know the count parameter is only Boolean or plusone.state returns on/off but is there something like plusone.value? ( i tried it, it's undefined)
Thanks
Download the following url: https://plusone.google.com/u/0/_/+1/fastbutton?count=true&url=URLENCODED_URI via your favorite automatic method (curl, wget, file_get_contents, etc...)
URLENCODED_URI is the site you which to know the number of +1's for, e.g. http://www.google.com
For example, fetch the URI https://plusone.google.com/u/0/_/%2B1/fastbutton?count=true&url=http://www.google.com/ and locate the first occurance of window.__SSR = {'c': 32414.0 ,'si'. Preferably use regexp for this, but I'll leave the implementation to you and your chosen programming language.
The float number following 'c' is the number of +1's the site have. For google.com this is 32.414. Don't worry about it being a float, it is allways an integer in float format, so you can safely convert it to an integer.
There is an undocumented API for this described here - http://www.tomanthony.co.uk/blog/google_plus_one_button_seo_count_api/
Directions for +1 button tracking can be found at http://yoast.com/plus-one-google-analytics/
On the button creation screen, create a js callback then track the clicks using Google analytics with the following code:
<script type="text/javascript">
function plusone_vote( obj ) {
_gaq.push(['_trackEvent','plusone',obj.state]);
}
</script>
Alternately, use the javascript callback to track it any way you wish.
