@Saffith is there a way to retrieve the config from enemy editor? for ghosted enemies attached to builtin enemies?

 

basicly what I'm asking is is there a way to retrieve the following from the enemy editor

- HP

- Damage

- W. Damage

- Random Rate

- Halt Rate

- Homing Factor

- Step Speed

- Etc...

 

I ask this so that I can set my ghosted attributes to what they are defined as

You can access this information from the standard npc class found in std.zh then pass it to the appropriate ghost variables.

[Shadowblitz16]

how though I don't see anything regarding the options in the enemy editor listed in on the zc wiki

I see it it was in the zscript.txt file

 

however I was wondering how do I check for the hp of the ghosted enemy?

do I just use the npc parameter directly?

found this one too (inside ghostzh.txt)

 

also is there a way to disable collision with link? its for a leever.

found out that I just do  "ghost->CollDetection = false;"

 

however I would like to know how to access the ghosted ffc script's variables in outside functions

I tried passing "ffc this" and "npc ghost" to the function but the compilers say that it doesn't have that pointer type.

What exactly are you trying to access and from where?

 

Ghost has a mix of global and local variables.  You can pass all of them as arguments into a function.

Here is a snip-it from one of my enemies as an example of accessing and passing information from/into a function.

[...]
while(Ghost_Waitframe(this, Dragon, true, false)){
		
			//Dragon Movement.
			SegmentMove(DragonID, Rate, Dragon, this);
			
			//Update Timer and Rate.
			if(Rate == 0){
				Rate = 180;
			}
			else{
				Rate--;
			}
		
		}
[...]

void SegmentMove(int DragonID, int Rate, npc Dragon, ffc this){

	int X = Dragon->X;
	int Y = Dragon->Y;
	int Z = Dragon->Z;
	int X2;
	int Y2;
	int Z2;
	float DragonStep = Dragon->Step;
	
	//Find step speed
	for(int a = Screen->NumNPCs(); a > 0; a--){
		npc Temp = Screen->LoadNPC(a);
		if(Temp->isValid()){
			if(Temp->ID == Dragon->Attributes[1] && Temp->Misc[0] == DragonID){
				DragonStep -= 5;
			}
		}
	}
	
	if(!Ghost_CanMove(Ghost_Dir, DragonStep/100, 2) || Rate == 0){ //Find new direction.
		Ghost_Dir = Rand(0, 7);
	}
	else{
		Ghost_Move(Ghost_Dir, DragonStep/100, 2);
	}
	
	for(int Segment = Dragon->Attributes[0]; Segment >= -1; Segment--){
		for(int a = Screen->NumNPCs(); a > 0; a--){
			npc Temp = Screen->LoadNPC(a);
			if(Temp->isValid()){
				if((Temp->ID == Dragon->Attributes[1] || Temp->ID == Dragon->Attributes[2]) && Temp->Misc[0] == DragonID && Temp->Misc[1] == Segment){
				
					//Check if Distance is greater than 16.
					if(DragonCheckDistance(X, Y, Temp)){
						return;
					}
				
					//Save this segment's pos.
					X2 = Temp->X;
					Y2 = Temp->Y;
					Z2 = Temp->Z;
					//Set this segment's pos.
					Temp->X = Temp->X + (X - Temp->X); // /2
					Temp->Y = Temp->Y + (Y - Temp->Y); // /2
					//If Tail, set new direction.
					if(Temp->Misc[1] == -1){
						if(Temp->X == X2 && Temp->Y < Y2){ //DIR_UP
							Temp->Dir = DIR_UP;

					//Move saved [X,Y,Z] to Stored values.

@cavthena I'm trying to access custom variables that I have defined within a the ghosted ffc script  in a function outside the ghosted ffc script.

[Saffith]

You're gonna have to be more specific. Could you post the relevant code?

[Shadowblitz16]

I can post an example

//This enemy behaves like a Leever, but homes in on Link whenever it's above ground.
// This approximately recreates the behavior of Leevers in Link's Awakening,
// among other games.
//
//Enemy Attributes Used:
// -Step Speed: Determines speed (standard: 50)
// -Misc. Attr. 1: Frames that the enemy will spend underground (default: 60)
// -Misc. Attr. 2: Frames that the enemy will spend aboveground (default: 120)
// -Misc. Attr. 11: Combo index for enemy graphics
// -Misc. Attr. 12: FFC Script Slot
//
//The combos must be four consecutive combos:
// 1. Initial surfacing combo
// 2. Second surfacing combo
// 3. Above ground combo
// 4. Below ground combo (usually blank)
//The combos play in the order 4-1-2-3-2-1-4-1-2-3... etc.

//Misc. Attribute Indexes
const int Z4LEEVER_COMBO_INDEX = 10;
const int Z4LEEVER_UNDER_TIME_INDEX = 0;
const int Z4LEEVER_ABOVE_TIME_INDEX = 1;

int angle;


ffc script Ghosted_Z4Leever {
    void run(int enemyID) {

        npc ghost;
		int combo;
        float step;
        int belowTime;
        int aboveTime;
        float lastX; //<-- defined in the ffc script
		
		//Initialize
		ghost = Ghost_InitAutoGhost(this, enemyID);
		Ghost_SetFlag(GHF_NORMAL);
		combo = Ghost_GetAttribute(ghost, Z4LEEVER_COMBO_INDEX, 0);
		step = ghost->Step/100;
		belowTime = Ghost_GetAttribute(ghost, Z4LEEVER_UNDER_TIME_INDEX, 60);
		aboveTime = Ghost_GetAttribute(ghost, Z4LEEVER_ABOVE_TIME_INDEX, 120);
			
		while(true) {

			
			//underground
			Ghost_Data = combo+3;
			ghost->CollDetection = false; //Make ghost intangible
			Ghost_Waitframes(this, ghost, true, true, belowTime);
			Change_Pos(this, ghost, Link->X, Link->Y, step);
			
			//surfacing
			Ghost_Data = combo;
			Ghost_Waitframes(this, ghost, true, true, 10);
			Ghost_Data = combo+1;
			Ghost_Waitframes(this, ghost, true, true, 10);
			
			//aboveground
			Ghost_Data = combo+2;
			ghost->CollDetection = true; //Make ghost tangible
			for(int i=0; i<aboveTime + Rand(30, 60); i++) {
				Ghost_MoveTowardLink(step, 0);
				Ghost_Waitframe(this, ghost, true, true);
			}
			
			//digging
			Ghost_Data = combo+1;
			ghost->CollDetection = false; //Make ghost intangible
			Ghost_Waitframes(this, ghost, true, true, 10);
			Ghost_Data = combo;
			Ghost_Waitframes(this, ghost, true, true, 10);
        }
    }
}
void Change_Pos(ffc this, npc ghost, int x, int y, int step)
{
	bool canSurface = false;
	lastX = 0; //<-- accessed in the external function
	
	while(!canSurface)
	{
		if (Ghost_X > x - 32 && Ghost_X < x + 47) Ghost_X = Rand(0, 304);
		if (Ghost_Y > y - 32 && Ghost_Y < y + 47) Ghost_Y = Rand(0, 160);
		
		if (((Ghost_X < x - 32 || Ghost_X > x + 47) && (Ghost_Y < y - 32 || Ghost_Y > y + 48)) && (Ghost_CanMove(Ghost_Dir, step, 0)))
			canSurface = true;
		else
			canSurface = false;
	}	
}

[Saffith]

You can't access a local variable declare in another function. If you want Change_Pos to have access to lastX, you need to pass it in as an argument. If it needs to set lastX, it can return a value.

[Shadowblitz16]

ok how about a slime split? the problem I have is checking if the slime is dead in the middle of script execution

I would just check if its hp is lower then 0 in all my functions but I don't know how to get past the wait frame functions

 

Edit: I also can seem to figure out how to access spawned gel ghosted variables and how to check for collisions between two gels

[Shadowblitz16]

is there a reason I can't get Ghost_DeathAnimation to set my zols death animation to nothing?

also how do I make the death effect stop falling when my enemy is dead?

 

here is my code

	if (Ghost_HP <= 0)
		Ghost_SetFlag(GHF_NO_FALL);
	else
	if (Ghost_GotHit() && splits)
	{
		npc gel1 = Screen->CreateNPC(enemy);
		npc gel2 = Screen->CreateNPC(enemy);
		
		gel1->X = Ghost_X - 8;
		gel1->Y = Ghost_Y;
		gel2->X = Ghost_X + 8;
		gel2->Y = Ghost_Y;
		
		Ghost_DeathAnimation(this, ghost, 128);
		Ghost_HP = 0;
	}
	//Something here to make enemy stop falling

Will there be an update to this video:

or is it largely still accurate?

[Saffith]

For something like that, you probably want to make your own Waitframe wrapper. Something like

void ZolWaitframe(ffc this, npc ghost)
{
    if(!Ghost_Waitframe(this, ghost, true, false))
    {
        // It's dead at this point; do whatever
        Quit();
    }
}

is there a reason I can't get Ghost_DeathAnimation to set my zols death animation to nothing?

If you don't want an animation, don't call the function. If you want to prevent even the regular death graphic, move the enemy offscreen so it's silently deleted.
 

also how do I make the death effect stop falling when my enemy is dead?

Do you mean how do you get your script to keep running? If the fourth argument to Ghost_Waitframe() is false, the script will keep running after the enemy dies.

I could perhaps update it. It's still accurate as far as it goes, but the new options to read data from the enemy's name are probably worth demonstrating.

@Saffith

how do I change the fake z shadow on an enemy?

I have small slimes that use small shadows however I don't see anyway of doing this

 

Edit: also does ghost.zh use the npc->Attributes[]?

I was wondering since I am getting weird values when reading them

Edited by Shadowblitz16, 04 January 2017 - 07:08 PM.

[Saffith]

The shadow settings are global, shared by all enemies. If you want one enemy to have a different shadow than others, you'll have to draw it yourself.

npc->Attributes[] is only used to read AutoGhost data. But it's read-only, so there's nothing I could be doing to change the values, anyway.

[Shadowblitz16]

@Saffith how do I turn the ghost's shadow off so I can manually draw it?

also how do I set the ghosted npc's position to a combo found by FindSpawnPoint()?

it looks like it returns a combos 1d position but I don't know how to convert the npc's 2d position to 1d.
