Hello there,
I apologize ahead of time if the solution to my problem is so simple I should have seen it earlier - for some reason though, I cannot (for the life of me) seem to get my SystemBase scripts to execute/register ANY code/input!
For example:
I follow this video to start using prefabs:
https://www.youtube.com/watch?v=m9YAxRhCZ8M&t=459s&ab_channel=TurboMakesGames
But got stuck at Input.GetKeyDown(KeyCode.A) - as mine did not want to register/execute!
I tried changing a few things to just get my code to debug a log at least, but still nothing~
I’m at a loss - if anyone is able to assist me it would be greatly appreciated!
Sincerely,
Bakos13
PS. I googled my issue but it seems no one else is having it! aha… so… Where did I go wrong!
I know I installed all the required ECS packages as instructed in the video.
-
com.unity.rendering.hybrid (which installs all pre-requisites for entities, mathematics, etc)
-
com.unity.physics
-
com.unity.netcode
My SystemBase script for spawning entities via prefab:
using Unity.Entities;
using Unity.Mathematics;
using Unity.Transforms;
using UnityEngine;
using Random = Unity.Mathematics.Random;
[UpdateBefore(typeof(TransformSystemGroup))]
public partial class gameController : SystemBase
{
private Entity _playablePrefab;
private Entity _capsuleSpawner;
private Random _random;
private float3 _minPos = float3.zero;
private float3 _maxPos = new float3(50, 0, 50);
private BeginSimulationEntityCommandBufferSystem _ecbSystem;
protected override void OnStartRunning()
{
Application.targetFrameRate = 30;
_playablePrefab = GetSingleton<Playable>().Value;
_random.InitState(4554);
_ecbSystem = World.GetOrCreateSystem<BeginSimulationEntityCommandBufferSystem>();
_capsuleSpawner = GetSingletonEntity<LastSpawnedPlayable>();
Debug.Log("1");
}
protected override void OnUpdate()
{
if (Input.GetKey(KeyCode.A))
{
Debug.Log("A");
var newPlayable = EntityManager.Instantiate(_playablePrefab);
SetSingleton(new LastSpawnedPlayable { Value = newPlayable });
var randPos = _random.NextFloat3(_minPos, _maxPos);
var newPos = new Translation { Value = randPos };
EntityManager.SetComponentData(newPlayable, newPos);
Debug.Break();
}
if (Input.GetKeyDown(KeyCode.S))
{
var ecb = _ecbSystem.CreateCommandBuffer();
var newCapsule = ecb.Instantiate(_playablePrefab);
var randPos = _random.NextFloat3(_minPos, _maxPos);
var newPos = new Translation { Value = randPos };
ecb.SetComponent(newCapsule, newPos);
}
var lastSpawned = GetSingleton<LastSpawnedPlayable>().Value;
if (lastSpawned != Entity.Null)
{
var lastPos = GetComponent<Translation>(lastSpawned);
var upPos = new float3(25, 25, 25);
Debug.DrawLine(lastPos.Value, upPos, Color.red);
}
}
}
