Trouble updating material property from script with SetFloat
Hello, I am trying to update a variable in a custom texture from a c# script.
Shader "UCLA Game Lab/Wireframe/Single-Sided"
Properties
{
_Color("Line Color", Color) = (1,1,1,1)
_MainTex("Main Texture", 2D) = "white" {}
_TravelY("Travel Y", Float) = 0
}
SubShader
{
Pass
{
Blend SrcAlpha OneMinusSrcAlpha
LOD 200
CGPROGRAM
#pragma target 5.0
#include "UnityCG.cginc"
#include "UCLA GameLab Wireframe Functions.cginc"
#pragma vertex vert
#pragma fragment frag
#pragma geometry geom
**float _TravelY;**
// etc
Here's is my c#
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MoveController : MonoBehaviour
{
public Material heightMapX;
public float speedX = 0f;
public float speedY = 0f;
// Start is called before the first frame update
void Start()
{
//heightMapX.EnableKeyword("_travelX");
heightMapX.SetFloat("_TravelX", speedX);
heightMapX.SetFloat("_TravelY", speedY);
}
// Update is called once per frame
void Update()
{
if (Input.GetKeyDown(KeyCode.UpArrow))
{
speedX += 5f;
heightMapX.SetFloat("_TravelX", speedX);
}
if (Input.GetKeyDown(KeyCode.RightArrow))
{
speedY -= 5f;
heightMapX.SetFloat("_TravelY", speedY);
}
}
}
The value is updating in the inspector..for both the script variable and the shader property. But it doesn't update in the actual scene unless I manually change values in the inspector.
Truncated the shader code to make it easier to scan, so ignore the lack of corresponding variables.
Any idea why the scene isn't updating?
