Hello guys, I am making a plataformer game and I was thinking, if the object (like an enemy) is too far away from the screen, there is no necessity to it execute any function like animate or move.
I am planning to create a game level that the player will need more than 6 minutes to go until the end. Therefore will be a lot of objects (scenario objects, enemies, traps, etc). So anyone know a good way to disable an object until the player enters in the object’s action radius.
For now, I am thinking to make a general script that uses a circle trigger collider, while the player is not inside of it, it will get all the components from the object(except this script component) and its children and disable then. What do you think? Thanks ;).
You can create a huge collider around your player. Once enemies/objects come within range, you can instantiate them. So you could use a simple place holder such as a cube or a transform, once the collision happens, instantiate the enemy on that spot. You could pass in a prefab to the script on to this spawner object so it automatically spawns the correct prefab.
TheHoboCoder: I am thinking this as a last alternative, split the level in minor levels.
Meltdown: This idea is like what MarkusB said, maybe this can be a good idea. I am thinking about also let one script on each other object that only activates the others components of the object while it’s inside of the huge collider. Something like:
function OnTriggerEnter (other : Collider) { var sm : ScriptManager = other.gameObject.GetComponent( ScriptManager ); if( sm != null ) sm.setObjectsFunctional(true); // this function make all the components of this object and its children active } function OnTriggerExit (other : Collider) { var sm : ScriptManager = other.gameObject.GetComponent( ScriptManager ); if( sm != null ) sm.setObjectsFunctional(false); // this function disable all the components of this object and its children except the ScriptManger }
You could add a script to the player, where he has a radius of the distance he can see objects.
In this case, if an object enters the radius, the script activate the object or render, whatever it is. When it comes out, turns off.
Well I think that the graphic part isn`t THE problem, since I can use the camera’s farClipPlane and etc. I am more bothered with the script processing like AI with objects that are too far away.
And about the cullDistances, what I read in the docs, it’s something like the farClipPlane, I don’t get how to use it instead of circle trigger colliders, can you give me a little example jsipich?
eem I read somewhere that is better to let the unity’s trigger collider make the detection work than use square distance or other thing to do this. Anyone heard this too?
I am stupid. I am facepalming myself as I type this.
I don’t know why but I read your post as “hiding” the entire object from view and not just “disabling” what that object (enemy, etc) does.
Yes - triggers would be the route I would use. I would create a bool that would turn the functions of the object on/off based on whether or not that trigger was collided.
Using an FPS like Resistance 2 for the PS3 as an example, the team created AI that would function differently based on distance from the player.
The closer you got to the enemy - the more advanced AI routines would run. Also - the AI routines would change based on wether or not that enemy was within view of the players FOV, as well.
This way enemies could still be “active” at further distances but not directly engaging the player. This was how they created massive battles with tons of enemies - the distance to the player was the driving factor for how advanced the AI routines were. This gave the “illusion” of pressure on the player.
Use this method, from what I know that’s the common practics of doing it. just don’t do at level junks, use it per object. Once the user enters the trigger, just enable the renderer + all scripts
I think that some objects like torches need to be activated some seconds before become visible, otherwise you can see a torch turning on of the nothing, like something supernatural
Well guys, I am trying to implement to trigger active area. But I am with a problem, when I want to get the scripts components I can only get the object itself, for example when i run this code with the dog enemy, it shows only “DogTop” on the debug log instead to show the 7 scrips that it has. Can some1 gimme a hand, i think that the problem could be in the lines 39-79 in the ProcessController.js
ProcessCoontroller (attach in everything that want to enable/disable):
#pragma strict
private var canProcess : boolean = true;
private var topParent : GameObject = null;
function Start()
{
// Getting the root from this object
topParent = transform.root.gameObject;
setProcessing( false );
}
function setProcessing ( b : boolean )
{
// Checking if need to change something
if( canProcess == b )
return;
// JavaScript script is a MonoBehaviour, C# and boo need to make it explicitly
var scripts : MonoBehaviour[] = topParent.GetComponents.<MonoBehaviour>( );
// Changing all scripts from the object
for( var script : MonoBehaviour in scripts )
{
Debug.Log( script.name + "top" );
if( script.name != "ProcessController" )
{
script.enabled = b;
}
}
// Getting all the children and doing the same
for( var i : int = 0; i < topParent.transform.GetChildCount(); i++ )
{
var t : Transform = topParent.transform.GetChild(i);
var go : GameObject = t.gameObject;
var scriptsChild : MonoBehaviour[] = go.GetComponents.<MonoBehaviour>( );
// Changing all scripts from the object
for( var scriptChild : MonoBehaviour in scriptsChild )
{
Debug.Log( scriptChild.name + "child" );
if( scriptChild.name != "ProcessController" )
{
scriptChild.enabled = b;
}
}
}
canProcess = b;
}
TriggerDetector (attach to some child with a trigger collider in the player):
Just use GetComponentsInChildren Method to get all scripts in the active object and all of it’s children.
It’s best to do this in Awake() and cache it in a member variable, so it doesn’t have big performance impact during the gameplay.
public class Blah : MonoBehaviour {
private MonoBehaviour[] scripts;
public void Awake() {
scripts = GetComponentsInChildren<MonoBehaviour>();
}
// P.S. It's a pretty bad idea to call an variable 'b'
public void SetProcessing(bool enable) {
foreach(MonoBehaviour script in scripts) {
script.enabled = enable;
}
}
}
Oh thank you Tseng, I made this changes in my code, but now I am getting all the object and children objects names instead of the their scripts names, do you have any idea what is wrong?
#pragma strict
#pragma downcast
private var canProcess : boolean = true;
private var scripts : MonoBehaviour[];
function Start()
{
var topParent : GameObject = transform.root.gameObject;
// Getting the scripts
scripts = topParent.GetComponentsInChildren.<MonoBehaviour>( );
// Set it to false
setProcessing( false );
}
function setProcessing ( bool : boolean )
{
// Checking if need to change something
if( canProcess == bool )
return;
// Changing all scripts from the object
for( var script : MonoBehaviour in scripts )
{
Debug.Log( script.name + "top" );
if( script.name != "ProcessController" )
{
script.enabled = bool;
}
}
canProcess = bool;
}
