Beginner C# problems

Unity Engine
1

Hey all,
I’m having a hard time using C# the way I thought it works, I was hoping someone could steer me in the right direction on this one.
This is a basic script to define a couple variables then utilize those variables.

using UnityEngine;
using System.Collections;

public class CharacterMovement : MonoBehaviour {

public int vertSpeed = 0.20;
public int rotateSpeed = 0.20;

void Update ()
{
if (Input.GetKey (“space”)) {
transform.Translate (Vector3.up * vertSpeed);
}
}
}

When trying to load this back to unity, I receive an error saying
" Constant value 0.2' cannot be converted to a int’ "

If “int” isn’t the right class, what is, and what would be the correct formatting for my use? Thanks all.

Vectors are floats. Start here.

you should watch all the scripting videos once a month for a year. it will make you way way way smarter. I still go back to them from time to time years later. not patronizing. Gametyme is right. There are things you will -not- understand right now you will two months from now, and so on.

and int cannot have a decimal. it is a solid number.
a float is a floating point value, and can have decimals
you want declare

float rotateSpeed = 0.2f;

if you don’t add the f it will be treated as a double and will not work.
read the tutorials. watch the videos. you will save yourself way more time than if you don’t, even if they seem time consuming.

Thanks for the indepth explanation. I will most definately take your advice onboard. These videos are the ones Gametyme has mentioned?

I suggest you, to learn the C# basics. There are ton of online open books. “If “int” isn’t the right class”, That are variables which saving your datas in memory at runtime. ^^

Seems like you just need to learn the basics. You’re driving a car not realising that handbrake and clutch exist :slight_smile:
