GUI index of (char) and CalcSize

[kiriri]

hey,
I need to separate 1 string into 3 as following:
string 1 needs to be from the beginning of the string to the x-th space
string 2 needs to be from the x-th space to the n-th space.
string 3 needs to be the rest.

I thought I could realize this by first writing an index of (char) action, and then getting the substrings based on the index.
However, there's scarcely even a single sentence about this on the api reference and I am somehow not getting started :S .
On top of that I want to output the strings as if they were one string, so I need to calculate their size, which I recon GUIStyle.CalcSize can do. But how can I reference a GUI to it? It's not like there are any GUI-variables in PlayMaker, so I'm somewhat at a loss.
I would really appreciate some help

Thanks,
kiriri

Hi,

 you should look at this thread for splitting string into an array and work with it then.

http://hutonggames.com/playmakerforum/index.php?topic=891.0

I would split your string in an array, and then access your 3 chunks conveniently with indexing in the array for the xth and nth split.

As for the calcsize, I guess i'ts going to be tricky in playmaker, I don't see right now how this can be achieved, maybe someone will step in with a solution.

bye,

wow that worked perfectly! I really have to learn all your awesome arrayMaker actions by heart
Now I'll just have to find a way to print the three strings as one flawless line... Anyways, thansk a lot, your action has brought me a lot closer to the goal

since I desperately need this calcSize to work, I thought I could achieve it by implementing it directly into the GUILabel FSM. However, as always, I'm having a lot of difficulties. Why isn't the following working?

Code: [Select]

GUILayout.Label(new GUIContent(text.Value, image.Value, tooltip.Value), style.Value, LayoutOptions);
GUIStyle go = style.Value;
Vector2 size = go.CalcSize(GUIContent);Sorry about my incomprehension, I really haven't quite grasped the concept of converting variables between playmaker and unity and the lack of any example for this function doesn't make it easier :S

Hi,

Yeah, ArrayMaker is mandatory in my opinion I made it because I needed it. Working with array is at the core of any programming whatever the subject.

 re calcsize, Allow me few days to work on that, I am sure we can work something out.

sounds great! For now I'll just have to write a hardcode script for the GUI print, but I fear that my employer wouldn't like it so I really am glad you're giving everyone such a great support

[jeanfabre]

Thanks,

 and don't hesitate to get back to me if I forget, the forum and demand it getting bigger and bigger, can't keep up now

undoubtably understandable
That's btw also the reason why I'm bumping my posts all the time. I'm normally no bumper you see.
So asking bluntly: Has anyone created a way of doing this? I know I have some actions lying around which I never share because they're to specific to help anyone but me.. maybe someone has made this already ?  

[jeanfabre]

Hi,

 Ok, not really able to find a way out of this as a pur action because I can't access GUIStyles. the GUIStyle is not a type that can be displayed in the action interface and it's not a type we can reference in a FSMObject variable so currently I am stuck with this, I can't see a way to do this with playmaker only unfortunatly.

 Bye,

 Jean

I see... maybe Alex can do something about this? Until then I surrender and stick to my hardcode for this :S
Is it possible to move this to the feature request forum?

[jeanfabre]

Hi,

 I sent an email about this to Alex already, we'll see.

 I hope for future update where we will have complete control over the action interface, that will open new perspective, basically allowing very powerful action ui.

bye,

Sorry for the delay. You're on the right track here, but you need to get the GUIStyle given its name:
http://docs.unity3d.com/Documentation/ScriptReference/GUIStyle-operator_GUIStyle.html

So this should work (untested):

Code: [Select]

// create the GUIContent
GUIContent guiContent = new GUIContent(text.Value, image.Value, tooltip.Value);

// get the named style from the current skin
GUIStyle style = GUIStyle(style.Value);

// get the size of the content if drawn with this style
Vector2 size = style.CalcSize(guiContent);
When I get a chance I'll make a CalcSize action, or maybe add Store Size to the GUI actions...

Hi,


 Thanks Alex, I missed that operator! the action is now up:

http://hutonggames.com/playmakerforum/index.php?topic=1864.0

a series of similar function is available, if you need them, don't heistate to request them:

Bye,
