Breath bar help

Unity Engine
1

Hi guys I didn’t know if I should post it here or in the GUI forum but I am having a problem with my breath script. I want my texture to cut off area, or gradient the decreases. At the moment it just shrinks, I was wondering if there is any way to do it in the free version or is it a pro function only.

hmmm never done this my self, but one way I would believe works in the free version is to draw semi transparent GUI images on the whole screen? otherwise I do think there is some fade in/fade out scripts available for the free version too, look around mate :slight_smile:

I think if you choose a shader with alpha u can probably fade it out

4

i dont think a shader work on a GUI does it?

I believe it does, I’ve made a mini map with shaders, however i do not know if it works in the free version.

Here is the code of the script that i have.

//Define variables
var underwaterLevel: float= 232.25;
var underWaterPlane: Transform;

static var curBreath : float = 100.0;
static var maxBreath : float = 100.0;
static var breathRegen : float = 0.175;
var breathBarTexture : Texture2D;
var breathBarLength : float;
var percentOfBreath : float;
//var myRect : Rect = Rect(0, 0, 100, 100);



function OnGUI () {	


	if (curBreath > 0){
	
//		myRect.yMin += breathBarLength;
//		GUI.DrawTextureWithTexCoords(Rect(((Screen.width/8)*7) - 100, 20, 100,100), breathBarTexture, myRect);

		GUI.DrawTexture(Rect.MinMaxRect(((Screen.width/8)*7) - 100.0,(20.0 / breathBarLength),(((Screen.width/8)*7)*1.0), 100.0), breathBarTexture);
   	}
}
 
function Update () {
	if (underWaterPlane.transform.position.y < underwaterLevel) {
	

		percentOfBreath = curBreath/maxBreath;
		breathBarLength = percentOfBreath*100;

		if(curBreath < 0) {
		curBreath = 0;
		}
		
		if(curBreath == 0){
			Player_Stats.curHp = Player_Stats.curHp - (breathRegen*4);
		}

		if(curBreath > maxBreath) {
		curBreath = maxBreath;
		}
 
		if(curBreath > 0) {
		curBreath = curBreath - breathRegen;
		}
	
	}
	else {
		curBreath = maxBreath;
		breathBarLength = 0;		
	}
}

Me and my friend are trying to work this out is there anyway we could have a mask that slides over it to make it look like it is decreasing. Or is our code the wrong way.

sure, but youre still gonna need to use a masking shader.

Cropping a texture in gui is easy, use Groups

for results like this

To fade it isntead, you will need to use a shader

9

would this work doing it vertical as well top to bottom

10

Cropping a square texture is easy ^

Cropping a round texture you still need to use a masked shader.

Look at texture mask here: http://wiki.unity3d.com/index.php/Shaders

11

Oh okay I am guessing that I cant use the GUI to call the shader on the texture of the object i would have to create a object instead?

12

is there anyway to reverse it so it fills up from the top to the bottom i am getting really confused on how to do that bit

13

Cropping a round texture in GUI is easy, use Groups

for results like this

For a fade instead, you will need to use a shader

14

hey is there anyway you give me the script of how you did that? So i can figure how to work it with my own script

15 
   		GUI.DrawTexture(new Rect(5, 5, img2.width, img2.height), img2); //draw the background image
		GUI.BeginGroup(new Rect(5, 5 + img1.width-someValue, img1.width, someValue)); //this group crops the top image
		GUI.DrawTexture(new Rect(0, someValue-img2.height, img1.width, img1.height), img1);//draw the top image
		GUI.EndGroup();
16

Thanks for that it really helped with me understanding how it works and it work well with my other scripts thanks

17

interesting.

pity youre using the built-in GUI

18

But doesnt NGUI cost?
