It looks like a bug but in fact is a side effect of the way the Spawn action is implemented. If I fixed it, it would break other things. So I'm afraid you'll just have to use Sully's workaround.

I think it's a good default, since you shouldn't rely on exact float comparisons anyway. However, the system str expression won't do any rounding, so if you want to see the un-rounded value you can do str(value).

We're hoping to add drawing tools to make this easier in future. In the mean time you could try asking the developers of these apps to enable proper alpha support! It's really old fashioned to not support alpha. There should at least be an option in the program to export your artwork with transparency using a color key. As I said, Construct 2 itself does not use any color key.

Use the 'set vector Y' action. A negative Y value will make them jump up, even if not on the ground. So if your jump strength is 500, setting vector Y to -500 has the same effect. To stop them being able to jump infinitely, you probably want to set a flag when the player lands on the ground, and clear it when they do their double jump, and make sure the flag is set before allowing a double jump.

Great example b781rev! One thing though - on this line in the PHP:

ysql_query("UPDATE ajax SET ajax_score = '$score', ajax_level = '$level'

WHERE username = 'b781rev'");

I don't know PHP very well, but it looks vulnerable to a SQL injection hack. If you request the AJAX URL with this for the score:

0';DROP DATABASE;

then you substitute that in to the SQL command and it wipes the database. You should be very careful about SQL injection - many, many sites have been hacked by that.

The disappearing thing is a little bug, it's fixed in the next build. It actually disappears for one tick only, but if nothing else is going on then the screen is not redrawn.

If you need mirroring not based on changing the angle, I think the easiest thing to do is actually just to mirror it in the animation editor and set the animation.

Oh, if you want to display the framerate, just use the fps system expression! E.g. set text object text to fps

Can you link us to the game so we can try it ourselves? Possibly provide the .capx too? Which browser are you using as well? Is it any better in different browsers?

You might be interested in the article Delta-time and framerate independence which shows you how to make a game keep running at the same speed even if the framerate dips.

HTML5 canvas doesn't support negative widths or heights so I had to change how it works - now it uses the angle. As Kyatric says it only works in HTTP preview mode - if you are still having issues maybe post your .capx?
