You have to use the newline expression when setting text with events. It's the same throughout C2.

ex.

"first line" & newline & "second line."

Haha indeed...

Anyway I wish you luck. A program with more stock gui manipulation may be helpful for your case. If you don't mind diving into coding I hear c# has nice gui capabilities and good gui designer to boot. C2 could likely do the kinds of programs you had in mind but as you may have noticed you'd have to make most of the gui stuff from scratch. Which isn't too bad since it gives you finer control of what it does.

There is no json plugin. One option is making your data match the format os some plugin's .toJSON expression then loading that back into the plugin. You can also use the "execute javascript" action and expressions of the browser object.

Here's a starting point:

It's then your responsibility to make sure you have inputted everything correctly otherwise you will get errors.

Refer to this tutorial for more info:

K, I think the answer is yes as I don't get any errors.

yep.

o I use Ajax for this, or should I create functions in code to do these?

Whichever you can use to get it to work. I'm not too familiar with ajax calls but it may be simpler to use the plugin if there are edge cases it handles. But again I have a knowledge gap about that that you can probably find alot of resources about with google.

You need to uses double double quotes quotes to put a single double quote in a string.

It's the equivalent of using \" in other languages.

Load it into the array object using the "load" action and then you can access them with the array expressions.

ex.

First item:

Array.At(0)

2nd:

Array.At(1)

The simple formula for a spring force is F=kx, where k is the strength of the spring and x is the difference of length from a rest length.

Here is a capx of it in action.

https://dl.dropboxusercontent.com/u/5426011/examples20/spring_physics.capx

I also added damping which uses the formula F=-cv, where c is the damping strength and v is the object's velocity along the length of the spring. In the capx the formula looks a bit much because of a vector projection but it works.

/examples20/rope_loop.capx

An extension of my previous physics rope example. It now supports multiple ropes and rope loops. Also they are created around sprites placed in the editor for easier setup. A tip for anyone adding joints to newly created objects: you need to wait a tick so box2d updates the object's position and rotation.

Wouldn't setting the layer's angle to the player's angle work?

Without you're cap I can only guess but is the sprite's "invisible at start" property checked?

Feel free to use/fork/modify this plugin, I don't mind at all. I'd have to look in to setting up a github but it's not high on my priorities list. And cool icon, thanks, I'll be sure to include it in my next update.

Look in the plugins section of the forum, there's a plugin there that does that and I think it's actually called "multiline textbox".
