Need a bit of help in coding

[Jacen]

Hi ppl!

I'm new to scripting and I can't manage to make a ONSPowerCore to trigger an event when it has taken damage and I would like help.
I wanted to make it like RedActivationName, BlueActivationName, and DestroyedEventName in the Events tab of Actor Properties.

The most I could figure is the code should have TriggerEvent(); and belong somewhere in Function TakeDamage() of ONSPowerCore.

That's pretty much all there is to it. (Of course, apart from defining a new variable for the event name.)

I'm surprised that I figured that right but I'm not familiar with coding (I only know the basics of C++) and I tried writing it but it did not work. I was only able to interpret its meaning.
Could you write down a step by step instruction, please and thanks

If you're not familiar with programming, I'd recommend learning a little more before trying something as specialised as UnrealScript. Try learning a bit of Java; UnrealScript's syntax is largely very similar to that of Java.

Or you could just try an UnrealScript tutorial; I've seen some posted on this forum a few times.

If you already have some C++ experience, "UnrealScript compared with other languages" might give you an overview of what is different in UnrealScript.

Thanks for the suggestion guys. I tried writing it again. And here's what I got:

class ONSPowerCore extends DestroyableObjective

var(Events) name            TakeDamageEventName;

function TakeDamage(int Damage, Pawn instigatedBy, Vector hitlocation, Vector momentum, class<DamageType> damageType)
{
  // All the original code before
  if ((DamageEventThreshold > 0) && (AccumulatedDamage >= DamageEventThreshold))
  {
    		TriggerEvent(TakeDamageEvent,self, InstigatedBy);
    		TriggerEvent(TakeDamageEventName,self, InstigatedBy);   // What's self and InstigatedBy
    		AccumulatedDamage = 0;
  }
  // All the original code after
}

This was change in my map using UnrealEd but the TakeDamageEventName was not in the Events tab. I noticed when I compiled changed using the UnrealScript Editor, the bar on the bottom was white. Did I do anything wrong?

You don't want to edit any existing code. Really.

You never change anything that came with the game, you always add to it.

I do not think it compiled since the bar did not say anything like "Successful." Thanks for the warning. I was afraid to subclass it because I think it might corrupt the onslaught game and bot AI.
I'm still stuck with same problem anyways because it did not seem to work. Any help?

I wrote this instead

class MyONSPowerCoreBlue extends ONSPowerCoreBlue
	placeable;

var(Events) name         TakeDamageEventName;

function TakeDamage(int Damage, Pawn instigatedBy, Vector hitlocation, Vector momentum, class<DamageType> damageType)
{
        // All the original code of ONSPowerCore before

    	if ((DamageEventThreshold > 0) && (AccumulatedDamage >= DamageEventThreshold))
    	{
    		TriggerEvent(TakeDamageEvent,self, InstigatedBy);
		TriggerEvent(TakeDamageEventName,self, InstigatedBy);
    		AccumulatedDamage = 0;
    	}
	
        // All the original code after
}

Usual question for posts like that: How do you know it doesn't work, what do you expect to happen and what exactly happens when you try?

[Jacen]

My goal is to create a "TakeDamageEventName" for the two power cores of an onslaught game which will trigger an outside event picked up by a Action_WaitforEvent in a Scripted Trigger.
Here's what I did:
I created a subclass of ONSPowerCoreBlue and Red with the code written above named "MyONSPowerCoreBlue" and "MyOnsPowerCoreRed" and compiled it.
Then I added the two cores into my level. When I opened the actor properties of each core, the "TakeDamageEventName" was there. After that, I matched the name of the "TakeDamageEventName" with Action_WaitforEvent in a Scripted Trigger (The next order of sequence is to trigger a mover).
I play tested it, shot the power core, mover didn't move.
