Hello, under what license is this script released under ? Thank-you.
if this was under license, it would have been stated and it is highly likely it wouldn't have been posted so openly
Sorry I don't usually bother licencing gists.
Consider it an MIT licence. That's what I normally use for repos.
how do I put this in an apk?
You mean an Android app?
You might want to start with a tutorial on building Android apps with Unity.
I love the code! I revised it to put the player back at their original position afterwards to keep them from being distracted in the game. However, it does work with some modifications with the 3rd person script. I only kept the rotation code so I could free look without the rest of the 3rd person script interfering. It works perfectly with my other code! Using Unity 2019.3 because my models from Character Creator do not work with Unity 2020 and above yet (something is buggy still about 2020 in my opinion).
Awesome. I'm glad this code is still useful!
Great thing! Exactly what I expected. Thank you.
This is awesome, exactly what I needed, thanks! By the way, I think the only namespace you need to include is UnityEngine, the rest doesn't seem to be necessary ;)
Cool, thanks for letting me know! The other stuff is just standard .NET imports that are included by default ;)
I wanted to have Q and E behave same like Unity does, actually for me it's the other way round.
/// <summary>
/// Normal speed of vertical camera movement (keys Q,E).
/// </summary>
public float verticalMovement = 10f;
and use it for Q and E
if (Input.GetKey(KeyCode.Q))
{
transform.position = transform.position + (transform.up * verticalMovement * Time.deltaTime);
}
if (Input.GetKey(KeyCode.E))
{
transform.position = transform.position + (-transform.up * verticalMovement * Time.deltaTime);
}
This is backward compatible solution; To get the Unity behavior you need to put -10 in the Properties Editor.
