how can i collect items that fills up a GUI??

Question

ok.. i already have a script for doing an array of words to put in to the GUI.

now .. i want the GUI to fill up as i collect words, letters, objects , etc..

so when i collected up to a certain amount of items...

the GUI will fill up as i collect..

[word collected] -> [++++GUI++++]

and what's the best type of GUI for this..??

some help, tips and solutions are appreciated..

thank you for your patience and attention..

Ok I'm going to attempt an answer without fully understanding the problem :)

   function OnGUI() {
      GUILayout.BeginArea(Rect(20,20,600,600)); //Use your own dimensions :)
      GUILayout.BeginVertical();
      for(var i = 0; i < totalItems; i+=10) //10 is max items per row
      {
           GUILayout.BeginHorizontal();
           for(var j=0; j<10 && i+j < totalItems; j++) 
           {
               GUILayout.Label(item[i+j]);  
           }
           GUILayout.EndHorizontal();
      }
      GUILayout.EndVertical();
      GUILayout.EndArea();
 }

Where items is an array or list of strings and totalItems is the number in it. You might be using an Array or ArrayList for items so in that case you can just replace totalItems with items.Length;

a rough assumption..

so...

i'll be starting off with =

var items : ArrayList;

var totalTiems : int;

something like that right..

anything i can do for any other functions, like Update, Start etc3??

thanks

Sure I can help with that - but I need to know what you'd like to do - do you want advice on writing Collision detection in a 3d world etc?

Your assumptions are fine - we can skip totalItems if we are using an ArrayList and just relace that in my example with items.Length.

owh.. ok... well i need help on the Collision/Trigger events to trigger the GUI..

as i collect items.. like a ball.. i'll keep on collecting it till i fill up the gauge in the screen.. so i can move on to the next level..

as i move to the next level.. the gauge remains the same.. but the items change per level.. and so as the difficulty of that level..

one question.. is it possible that the gauge can be shaped..?? like the gauge in forms of one simple word.. like BALL.. as i collect the items .. the word will slowly fill up according to the amount of items are collected..

i apologize if im disturbing you with my questions..

Hey no problem:

Right so I probably can't write it all for you, but I can certainly point you in the right direction.

To do the collision stuff

Make sure that all of the things that collider have a Collider attached - use a Box Collider or a Capsule Collider if you can - Mesh collider if you need high accuracy
You need to put a rigidbody on at least one of the components involved in triggering - probably the player. If you don't want to use physics to move it, make its isKinematic property true.
Write an OnTriggerEnter function on the player - it gets called with the thing the player hit. Use the .gameObject on that to get the item hit and add it to the list of things collected, then call Object.Destroy() on that gameObject (the one you got from the parameter to the trigger function).

So I think I see what you want now with the gauge - well you could fill something up, there would be a number of ways to do it - none of them very easy - I think my earlier answer will cover too much of the screen for you perhaps. So the best way I can think of is still a little tricky:

Using a paint package draw the word you want to fill in a texture - you can make it fancy this way
In your OnGUI use DrawTexture to draw it onto the screen - but draw only the % of the height that equals the current percentage complete

If you want to make that fancy - you could create two textures - one showing an outline and the other showing it filled. You would draw the filled one per my instructions above and then draw the outline (which needs to have a transparent background) over the top of it.

wow...

its way complicated than i thought..

lol..

i can understand the collision part...

the gauge thingy is a little unclear..

need some more lights on that area please...

thanks...
