Looks like optics test, image making with convex lens?

For me it looks like: For this particular need, you'll just have to resort using some real math. Since you know the angles and zero-Y crossings (the blue line) of each red lines, finding the image point it's not hard math at all.

If you'll know the focal distance, there's thin-lens formula at en.wikipedia.org/wiki/Lens_%28optics%29 that can directly give the x.cord of the point.

One idea - and it might not be a good idea - at the start of the game ask the player to click on the circle that is closest to the size of a pound coin or some other easily recognisable coin/thing, then using this "scale"...

Definitely not recommend using coins as a reference, since pounds are only used in UK. Even 1 Euro (or US quarter) are not easily available on all parts of the world.

When at layout-tab F4 does browser-preview as is stated on scirra.com/manual/64/keyboard-shortcuts.

To see Expressions panel, you'll need to be at event editor and start adding a new (or editing) an action that needs parameter (for example player sprite: set animation frame number) .. When that dialog box is open F4 open expressions panel.

IMHO it looks kinda unintuitive to use same hotkey to do totally unrelated things depending what part of the program one is. Especially since most of the time it just does nothing at all.

Yep. It is possible to add at least two sin-movements to same platform. I'm not sure if something like this will be enough, but at least it's easy to make.

Ok.

Thanks, and sorry for me being so snappy. I'm sure you'll do what you can and you don't have unlimited resources. These bugs just... Ah well, I can't really explain in English (especially using child-approved words) the feeling when I lose yet another post..

If I just remembered to do Ctrl-A and Ctrl-C each time I'm trying to reply.. Perhaps I learn.

As an efficiency point.. You don't need to check/set the health bar on each tick, just set it once after the bullet have been hit and health is lowered.

It would help a lot if you'd give the example capx ..

Where you store the enemy health? Is it a instance variable or global variable?

I have been reading this forum some time now and I've noticed that there apparently were some updates at the summer 2013? But IMHO it looks like the base forum code which seems to be from July 2011 ...

Seriously, using over 2 and half years old system that is known to be buggy?

webwiz.co.uk/web-wiz-forums/kb/release-notes.htm

" Version 10.01 (1st July 2011) "

I have not tested this, but would it be possible to add multiple Sine-behaviours to one ohject? Like one controlling X and another for Y position?

Besides that.. You can always count the time spend and make some functions to set X/Y positions..

Ooh.. Looks really interesting.

BTW the help link pixelrebirth.net/plugins don't work.

Obviously what you did was not successful. I'd recommend to re-install C2 and try again.

IMHO this does not sound like a BUG in C2.

I'd recommend you to remove that plugin you failed to install on previous 'bug report'. And re-install the Construct2 all new before posting more Bug reports.
