Barebone Baddy System Event Based

On IOS Servers using timeouts is really bad, so its recommended to avoid them when possible.

Here is just a bare-bone version of something that can be turned into a baddy system. Instead of the traditional timeouts it uses scheduleEvents and is event based with using flags like players.

Both classes attached.


Graal Script Code:
ExampleLevel NPC
const INIT_STATE "float";
const 
GLOBAL_STATE "float";

function 
onCreated() {
  
this.join("ai_module");
  
this.join("ai_variables");
  
this.savelocally true;
  
_set("maxhealth"100);
  
temp.maxHealth this._get("maxhealth");
  
this._set("health"temp.maxHealth);
  
// this.globalState = GLOBAL_STATE ;
  // this.enterState(this.globalState);

  
changeState(INIT_STATE);
}

function 
ai_enter_float() {
  
this.ani "idle";
  
this.aiPeriod 1;
}

function 
ai_execute_float() {
  
//logic here move?
  
this.ani "move";

Oh, this is actually a good starting place for a state machine (especially for gscript2, where making ai isn't easily done natively or ends up becoming spaghetti code)

Now I need to make an ai_execute_firing_my_lasers() function

there's nothing wrong with using a regular timeout.

polling (timeout, scheduleevent) is what's to be avoided if there's an applicable event (onplayerenters, onplayerhit, etc.) that can eliminate the need for a constantly running script.

the code would work exactly the same with a regular timeout!!!! unless u want to make inefficient baddies that tick every <0.05 sec.

Graal Script Code:
function onPlayerEnters() {
  
setTimer(this.aiPeriod);
}

function 
onTimeout() {
  if (
players.size() <= 0)
    return;
  
ai_execute();

  
setTimer(this.aiPeriod);
}

function 
enterState(temp.state) {
  if (
this.("ai_enter_"temp.state) != nil)
    
this.("ai_enter_"temp.state)();
}

function 
executeState(temp.state) {
  if (
this.("ai_execute_"temp.state) != nil)
    
this.("ai_execute_"temp.state)();
}

function 
exitState(temp.state) {
  if (
this.("ai_exit_"temp.state) != nil)
    
this.("ai_exit_"temp.state)();
}

function 
changeState(temp.state) {
  if (
this.currentState == temp.state) return;

  
this.exitState(this.currentState);

  
this.previousState this.currentState;
  
this.currentState temp.state;

  
this.enterState(this.currentState);

  
setTimer(this.aiPeriod);
}

function 
ai_execute() {
  
this.executeState(this.globalState);
  
this.executeState(this.currentState);

very nice, I just always had issues regarding latency when it comes to using timeouts with new Unity Engine with Graal. Sometimes when using timeouts NPCs would skip ticks and seems as if the NPC is hopping. I also noticed polling scheduleEvents hurt majorly as well.

I don't think you could say anything as you never worked on the Unity Client before. Unity client is more touche then the C++ Basic client. Last 4 months I been focusing on with Merlin on eliminating lag. And the number 1 culprit has been timeouts. And I'm not even talking about polling timeouts.

Well yes that is actually very true. However a timeout is continuous (always running, unless you add conditions for a return) while a scheduleEvent is being called when needed. I've seen people do things like setTimer(0) - Not even sure it works, but in my opinion it doesn't look clean at all.

You can use onTimeout() too lmao

The irony is that if you think I misread what you said then you clearly misread what I said

It's laughable that anybody would still want to make use of GScript even though somebody had the bright idea to actually write new client software.
