You are still using R152? That's quite old. I'd recommend you to download the latest Stable R158.2

scirra.com/construct2/releases/r158.2/download

To upload your code, firstly you need to make suitable version for web use.

• Select File-menu/Export.
• From the upcoming window, choose HTML-5 and then select where to save the files.

-> Construct will automatically make Index.html and necessary files.

After that, you should need to upload those exported files to some site where others can see them.

For a overly simplified answer: Physics performance is highly dependent on two things. CPU speed and Javascript implementation. On desktop systems we usually have (ballpark) 10* more powerfull processors and much more optimized Web browsers.

Also, always check performance and compatibility on real mobile devices. The XDK emulator may be somewhat sluggish, and may well be that some new mobile devices are performing better.

Also posting the example (capx) might help fir others to check if there's something really bad at your code.

Keepee, thanks for the doppler audio demo. I didn't knew that this kind of feature exists. Realizing once again, that there are so much I do not know about C2.

And yes, IMHO that is a valid bug

Its not much different than raycasting.

One thing I have noticed (and not needed that long) about this forum is that people seem to assume that the game developing system can do all the *thinking* for them.

Programs and toolkits like Construct, Unity etc. help carrying a lot of the burden and eliminate the lots of tedious ground work needed compared to coding the same game with C(++) or Javascript. But they aren't (at least yet) totally automated systems that can solve *everything* one may need during game making.

So, there are still some human game making skills needed, like logic and trigonometry. And this one definitely need the trig (and some example drawings) to be solved.

Is that FX -multiply added there on puropse? Without it, I think the blend modes work as I'd expect..

I have no idea what kind of effect you are looking for, but some blend modes depends on opacity of the images.

Are you perhaps running out of memory, if that iOS6 device is some older model it may just be unable to handle all the data?

Just testing C2 for non-game making. This RPN calculator works on FF and Chrome (+ Android browser) but not on IE (?)

Caveat.

On some systems max() and min() behave just the opposite way one would expect, and I've not tested this to be sure which one is right.

Otoh, that kind of mistake is usually quite easy to spot.

Limiting the output value should be quite easy with   max(500, 5 * distance (whateve))

Well.. I was thinking about Tempers and Gravitar, though I have no idea how well this system works on vector emulation.

Hi..

Just wanted to show this thingy I've been tweaking some hours. It's just simple 4 function RPN calculator (16 evens). It should be ok, but I've not tested it so well.

Edit.. For some reason I can't get it to work on IE.. ah well, not a biggie to me, but just to warn out if someone tries to.

Based what I have seen on real, released games during years. If you'll make nice working solution, there will be a lot companies willing to buy your code.   <img src="smileys/smiley38.gif" border="0" align="middle" />
