[Ethos] Boss scripts

**DivinityGang** · 10-06-2019, 06:32 PM

So I'm working on doing boss scripts for practice and I was looking at having a boss spawn some minions.

I want to either add these minions to an array and pick a random one to be the key that allows you to attack the boss again once it has been killed. What would be the best way to assign this role to a specific npc?

I'd also want all the minions in the area to die along with the key when it has been defeated how would I go about killing specific npcs in a region?

I was also looking at the demonic gorilla boulder throws as well as the great olm crystal projectiles falling from the sky, I was wondering how I'd look at implementing projectiles that randomly fall and deal damage

Thanks.

Edit:
So I've been thinking about it and I think the best way to do the minions would be something along these lines

I wanna say check the area for npcs (not entirely sure how to go about this part yet) and then adding all the minion spawns to an array.

looping through this array and assigning the key boolean to a random npc in this array.

hopefully that makes sense lol

A lot of different approaches can be utilized with what you are trying to accomplish, but let me see if I can outline some helpful bits for you.

* Assuming your core class is a manager for this boss, why not have a variable called keyNPC that is assigned the NPC instance of one of the minions. When a minion is killed you can check that keyNPC's index is equal to the NPC that has been killed and move forward from there.

* In terms of killing NPC's from a region you will need to look into how your NPCManager/NPCHandler/EntityHandler, whatever your source has as the core NPC functionality class, and see how it handles killing/destroying NPCs (and their instance).

* You will need to write a method in order to create generic projectiles that are separated from an entity.

As I said there are plenty of approaches to accomplishing this. Your class architecture of how you designed the boss script will inevitably determine how you go about this.

There's already this method

Code:

private void createProjectile(int x, int y, int offX, int offY, int angle, int speed, int gfxMoving,
			int startHeight, int endHeight, int lockon, int time) {
		// synchronized(c) {
		if (c.getOutStream() != null && c != null) {
			c.getOutStream().createFrame(85);
			c.getOutStream().writeByteC((y - (c.getMapRegionY() * 8)) - 2);
			c.getOutStream().writeByteC((x - (c.getMapRegionX() * 8)) - 3);
			c.getOutStream().createFrame(117);
			c.getOutStream().writeByte(angle);
			c.getOutStream().writeByte(offY);
			c.getOutStream().writeByte(offX);
			c.getOutStream().writeWord(lockon);
			c.getOutStream().writeWord(gfxMoving);
			c.getOutStream().writeByte(startHeight);
			c.getOutStream().writeByte(endHeight);
			c.getOutStream().writeWord(time);
			c.getOutStream().writeWord(speed);
			c.getOutStream().writeByte(16);
			c.getOutStream().writeByte(64);
			c.flushOutStream();

		}
	}

but obviously that's just one projectile and I'm wanting projectiles to continuously come down like 30 of them, and I can't figure out the best way to do this.

Then you should learn the java basics first. You can do that with simple loops or via a task system.

Solved this or still need advice? Sort of did something like this before.

Haven't achieved it yet

Still haven't figured out how to implement the crystals falling from the sky, any advice?

You could put the coords in an array and loop through them while calling the createProjectile() method for each coord being looped through in the array.

Can you elaborate?

/*We store the values of the designated tiles you want to launch the projectiles on here. 
They do not have to be hard coded like I did. You could create a method that loads tiles based on players present etc.*/

private Tile[] tiles = new Tile[] { new Tile(3333, 3333, 0), new Tile(3330, 3333, 0), new Tile(3332, 3333, 0) };
 
/*This is your method in boss class that launches the projectiles. It uses the values in the tiles array to determine
the location for the projectiles. You will have to input the values though. I just used 0's and 1's for example.*/

public void launchProjectiles() {
    for(Tile tile : tiles) {
        createProjectile(tile.getX(), tile.getY(), 0, 0, 1, 1, 1, 1, 1, 1, 1);
    }
}

// We have your createProjectile method here which is most likely in another class. I just have this here for visual.

private void createProjectile(int x, int y, int offX, int offY, int angle, int speed, int gfxMoving,
            int startHeight, int endHeight, int lockon, int time) {
        // synchronized(c) {
        if (c.getOutStream() != null && c != null) {
            c.getOutStream().createFrame(85);
            c.getOutStream().writeByteC((y - (c.getMapRegionY() * 8)) - 2);
            c.getOutStream().writeByteC((x - (c.getMapRegionX() * 8)) - 3);
            c.getOutStream().createFrame(117);

            c.getOutStream().writeByte(16);
            c.getOutStream().writeByte(64);
            c.flushOutStream();

        }
    }
}
