What math is that though?

Why does it require a y-component for the X layer and an x-component for the Y layer though? That seems intuitively odd.

Either way, using the CanvasToLayerX/Y fixed (or at least markedly improved) our spastic zoom and pan problem over using the Mouse.X and Mouse.Y.

I suppose it would be nice to have more precise and thorough documentation, although I would much prefer Scirra improving Construct into the website design arena over improved documentation.

Sort of. I am actually using it for a mouse-wheel-based zoom and pan (like Google maps) sort of thing.

I mostly want to know how that particular function works on the inside.

I have actually experienced something similar to this on a much smaller scale. I built our basic website using C2 ( currently living at http://50.112.151.9/home ), and I found that when using a time-based solution to having the menu items scroll-up, the speed at which it moves varies based on the machine and browser it is run on. I suspect this particular behavior is due to inconsistent clock timing.

I am not sure if this clock issue is related, but from a physical standpoint, any deviation in timing will result in micro-stutters, as they are described.

I ran that Jsfiddle on my machine also, and I only had 1 or 2 spikes and the rest was very consistent, so that is very likely browser-specific or perhaps even machine-specific.

I use it in practice, and as far as I can determine it gives the mouse coordinate in a local layer. For instance, I have a 10,000 x 10,000 (roughly) pixel canvas that I zoom in on. The Mouse.absoluteX and Mouse.absoluteY give you the mouse coordinates with respect to the screen. Mouse.X("layer") and Mouse.Y("layer") gives me the mouse coordinates with respect to my 10,000 x 10,000 px grid.

I am not really certain at all how the other expression works or what canvas it is mapping from. I assume it is mapping from the c2canvas to whatever layer I specify, but I don't see why it needs both x and y coordinates to do that.

Nobody knows how either of these work?

What is the difference between these expressions:

CanvasToLayerX("Layer 0", Mouse.AbsoluteX, Mouse.AbsoluteY)

and

Mouse.X("Layer 0")

?

I was using these in a large (like 10,000 x 10,000 px field) zoom and pan, and they behave much differently, despite the fact that they seem conceptually the same.

We currently hash the password and username together as a single unit before shipment on login, but this still requires the user's browser not to be compromised (which you can never be sure of). We are probably going to add a dynamically variant salt that the server will ship to the user's browser with a one time salt to hash with that will expire on a successful login.

Once the user is logged in everything is tracked via a session id which ties into a server-side cache containing all session details.

We will eventually go SSL, but for now we are in development.

Why don't you just use like Amazon Web Services free web servers (EC2), then you won't be making same origin calls.

However, I did get the Same Origin calls working on my local development machine.

Here are the relevant Apache settings:

<Directory />

AllowOverride None

Options FollowSymLinks

Header set Access-Control-Allow-Origin "*"

</Directory>

DocumentRoot "D:/Apache HTTPD 2.4.3/htdocs"

<Directory "D:/Apache HTTPD 2.4.3/htdocs">

AllowOverride None

</Directory>

However, I am only using Apache as a proxy gateway server, not the content delivery server. I run all requests through Apache back to a Tomcat serlvet container which feeds all game data.

Right, I'll tweak it to not do that. I want it to error off if the AJAX call fails. Thanks for your awesome plugin.

Does your Date plugin always grab the Date() from the System clock? I have been trying to get server time (in a UNIX timestamp format) via an AJAX call, but the clock seems to be displaying my local system time, not the server time that I gave the timestamp in your example.

Thanks.

We are making a MMO in C2 right now, but all of the hard work is done by Java servlets on the backend.
