Unity 4.6 - Is it possible to simply feed a public float into a button/slider/scrollbar?

Loving the new 4.6 Beta, but have a quick question regarding how events/On Value Changed thing works for the new UI tools.

I'm trying to control a player's speed *a public float variable*, but it's not showing on the drop-down menu?

I ended up having to feed it through a function, but it's an extra step which is a bit odd. Maybe I'm doing it wrong, could someone post the correct way on doing this?

Thanks.

 

Anyone?

 

Wrong forum, moved to developer preview.

 

Use properties.

 

If you add an event to the OnValueChanged() section of the Slider component, you'll be able to drop the object with your custom component (the one with the player speed variable) onto the left-most slot of that event. Then you can select MyCustomComponet > myFloatSpeedVariable from the dropdown.

Alternatively you could create and reference a function that would take the slider's normalized value and turn it into a more direct player speed value... like this:

Code (CSharp):

1. void ChangePlayerSpeed (float normalizedSpeed) {
2.     myPlayerSpeedFloat = normalizedSpeed * myPlayerMaxSpeedFloat;
3. }

 

Well, basically I'm trying to achieve what you said in your first suggestion, by using a simple variable like this.

Code (CSharp):

1. public float speed = 125.0f;

The problem is, when I check for my speed float variable on the OnValueChanged() function, it just doesn't show.

As for your second suggestion, that's what I'm using currently, but I'm wondering if the first suggestion is possible?

 

Nope, Sliders dont bind to fields. They can only call methods.

 

Oh right! I've never actually tried it with a field now that I think about it =-P

 

Just in case anyone here didn't know the difference between a property and a field (I didn't ) :

Code (csharp):

1. public float speed {get; set;}

this is a property and it CAN be bound to a slider

 

Oh wow! So attaching the below code to an new UI Slider....

Code (CSharp):

1.     public float gamma;
2.     public float UISetBrightness
3.     {
4.         get
5.         {
6.             return gamma;
7.         }
8.         set
9.         {
10.             gamma = value;
11.             RenderSettings.ambientLight = new Color(gamma,gamma,gamma,gamma);
12.         }
13.     }

AWESOMENESS!
