[C#] mono injector and question about code

[ElswordHackerAgain!]

hi guys at first i search any mono injector for my dll

and now the code , is that right or find you some errors?
btw: the dll is for an unity game

code:

 Spoiler

using System.Collections.Generic;
using UnityEngine;

public class MyUnityClass : MonoBehaviour
{
void OnGUI()
{
if (Event.current.type != EventType.Repaint)
return;
var spacing = 30;
var curY = 400;
for (int i = 0; i < 16; ++i)
{
var curPlayer = PlayerControll.Player[i];
if (curPlayer == null || curPlayer.go == null)
continue;
var output = string.Format("{0}: Pos={1} level={2}", curPlayer.Name, curPlayer.currPos, curPlayer.level);
GUI.TextArea(new Rect(15, curY, 200, 35), output);
curY += spacing;
}
}
private void DrawWorldText(Vector3 p, string name, Color color)
{
p.y = p.y + 2.5f;
Vector3 screenPoint = Camera.main.WorldToScreenPoint(p);
screenPoint.y = (float)Screen.height - screenPoint.y;
float single = GUI2.CalcSizeRes(name, 0, 8);
PlayerControll.Player[Client.ID].Name = "Playername xD";
GUI.color = color;
GUI2.DrawTextRes(new Rect(screenPoint.x - single / 2f, screenPoint.y, single, GUI2.YRES(8f)), name, TextAnchor.MiddleLeft, _Color.White, 0, 8, true);
GUI.color = Color.white;
}
}

I'm not sure what this piece of code is supposed to to.
AFAIK there is not even an Object called Camera in your scope.

Cydia Substrate (iOS) and Xposed Framework (Android) allow you to hook function. I guess that's what you want to do ?

this code does change the already exist functions in an unity game but i need an mono injector and i cant find any ...

1) it doesn't overwrite any functions.
2) You can't overwrite functions like this via injections.
3) There is no such thing as a mono injector because Mono is an API and gets called by the DAVLIC VM/Process
4) you obsiously ignored my first part because I already gave you the solution to inject your code
5) Alternatively you can inject the DLL via
i) ptrace
ii) malloc space and write your DLL path
iii) calculate modul base
iiv) get offset of each function that you want to hook
v) recalculate the jumps (writing a detour)
vi) force ARM to load your injected String(DLL path)

this code is 1:1 copy+paste and at the owner the code works without problems,but if i try to inject with normal injector game crashes only ...

You are trying to inject Bytecode, this wont work this way.
You can hack the bytecode of a Dll into loading your dll or inject nativ code, hijack the mainthread and call the needed Monofunction to load the dll
