# 2.Add the 3d assets + first few lines of code
1. If you want, drag a different material from Course Library > Materials onto the Ground object
2. Drag 1 Human, 3 Animals, and 1 Food object into the Hierarchy
3. Rename the character “Player”, then reposition the animals and food so you can see them
4. Adjust the XYZ scale of the food so you can easily see it from above
1. - Attach the script to the Player and open it
- In your Assets folder, create a “Scripts” folder, and a “PlayerController” script inside
- At the top of PlayerController.cs, declare a new
- \[SerializeField\]
- private float horizontalInput
- In Update(), set horizontalInput = Input.GetAxis(“Horizontal”), then test to make sure it works in the inspector
-
```c#
using UnityEngine;
public class Movement : MonoBehaviour
{
[SerializeField]
private float horizontalInput;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
horizontalInput = Input.GetAxis("Horizontal");
}
}
```
## 4.Move the player left-to-right
- here we can get our input with this basic code, we use \[SerializeField\] for sanitization and allow us to see the value in the inspection panel to make sure we didn't fck up lol
- Declare a new public float speed = 10.0f;
- here's my code
```
using UnityEngine;
public class Movement : MonoBehaviour
{
[SerializeField]
private float horizontalInput;
[SerializeField]
private float speed = 30.0f;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
horizontalInput = Input.GetAxis("Horizontal");
transform.Translate(Vector3.right * horizontalInput * Time.deltaTime * speed);
}
}
```
#### 5+6. Keep the player inbounds
- In Update(), write an if-statement checking if the player’s left X position is less than a certain value
- In the if-statement, set the player’s position to its current position, but with a fixed X location
- Repeat this process for the right side of the screen
- Declare new xRange variable, then replace the hardcoded values with them
- Add comments to your code or not lol
