Why color isnt working in JS

Unity Engine
1

I have a lerp system that changes the background color of the world to represent different times of day, but when I hit play the sky goes completely black, what did I do wrong?

#pragma strict

public var myCamera : Camera;

public var colorTime : float = 0;
public var turnTime = 0; /* 0 for day 1 for night */

var lerpedColor : Color = Color.cyan;
public var dayC : Color;
public var nightC : Color;

function Update() {
	lerpedColor = Color.Lerp(dayC, nightC, Mathf.PingPong(Time.time, colorTime));
	myCamera.backgroundColor = lerpedColor;
}

for DayC and nightC I went into the components and edited the color there, but the color still remains black when i hit play.

EDIT:
Here’s a pic of the problem with the component

I am not sure why lerped color changes to black and gets that odd long white line

Your alpha values for both dayC and nightC are 0, making it invisible.

3

Are you sure you want this?

Mathf.PingPong(Time.time, colorTime)

Especially because it makes no sense when colorTime is 0.

@Dantus How else should I approach this? A lot of that script is going off of the help someone else gave me…

@DanielQuick And how do I change the alpha?

If you look at the scripting reference entry, you’ll see that it will return a value between 0 and the second parameter. In this case, since you are getting a value to use in a Lerp, you want a value between 0 and one. This means that the second parameter should be 1.

The same way you change the colors, there are 4 slides. Red, Green, Blue, and Alpha

6

So you mean that it should be (Time.time, 1) ?

colorTime is a variable I have it makes so it takes 225 seconds to get to…

Oh in the script I have colorTime set to 0.
I made it 225 through the component side panel thing

Thanks, worked perfectly! I feel kinda stupid lol.

Then the first parameter should be Time.time/colorTime

8

lerpedColor = Color.Lerp(dayC, nightC, Mathf.PingPong(Time.time/colorTime));

ERROR:

The best overload for the method ‘UnityEngine.Mathf.PingPong(float, float)’ is not compatible with the argument list ‘(float)’.

I said the first parameter, not the only parameter.

You need to learn to use the scripting reference and follow the error messages instead of blindly testing things out.

sorry
