Modding / Re: Misc modding questions that are too minor to warrant their own thread

« on: January 24, 2013, 12:18:32 AM »

Nice catch thereEnder nerd code, didnt even see that one. Okay heres another, trying to make a shot bounce off sheilds. i can spawn the shots by this:

Code

		if (shieldHit && target instanceof ShipAPI)
		{
			float angle = ((float) Math.random() * 360f) - 180f;
			engine.spawnProjectile(projectile.getSource(), projectile.getWeapon(), 
								projectile.getWeapon().getId(), point, angle, null);
		}

Now i know that i can get the location of the projectile by useing "point" and i can get the location or the target by useing target.getLocation(), but can anyone show me how to calculate the angle from point to target.getLocation()? Im asumeing theres trig involved >_<

Sometesting of the code shows that

Code

            particleVelocity.x = ((float) Math.random() * 10f); //give the particle a random velocity.
            particleVelocity.y = ((float) Math.random() * 10f); //Math.random() results in a number between 0.0 and 1.0

are causeing the problems. As for the corect code? not sure ill look into it.
Oh also the damage spawning line of code, you had "engine" as the source of the damage. I changed that to projectile.getSource(), dont know if that has any relevance though as it didnt fix the problem till i got rid of the .x .y lines of code.

EDIT*
After some testing i got the code to work... as for why? i dont know. Maybe its because i set up the particalVelocity vairable useing getVelocity()... not idea. Well:

heres what i used that worked without error:

Code

package data.scripts.weapons;

import java.awt.Color;

import org.lwjgl.util.vector.Vector2f;

import com.fs.starfarer.api.combat.CombatEngineAPI;
import com.fs.starfarer.api.combat.CombatEntityAPI;

import com.fs.starfarer.api.combat.DamagingProjectileAPI;
import com.fs.starfarer.api.combat.OnHitEffectPlugin;
import com.fs.starfarer.api.combat.ShipAPI;

public class ExtraHitEffect implements OnHitEffectPlugin {

	public void onHit(DamagingProjectileAPI projectile, CombatEntityAPI target, Vector2f point, boolean shieldHit, CombatEngineAPI engine) {
		if (!shieldHit && target instanceof ShipAPI)
		{
			//set vairables for the partical. Could do inside the call but will do it here
			float particleSize = 15f;
			float particleBrightness = 1f;
			float particleDuration = 2f;
			Color particleColor = new Color(85, 25, 215, 255);
			Vector2f particleVelocity = projectile.getVelocity(); // Lines below were causing issues, so i replaced them for testing
                        particleVelocity.x = ((float) Math.random() * 10f); //give the particle a random velocity.
                        particleVelocity.y = ((float) Math.random() * 10f); //Math.random() results in a number between 0.0 and 1.0
			
			//set damage vairables
			float damageAmount = projectile.getDamageAmount() * .25f; //extra damage is 1/4 of full
			float empAmount = projectile.getEmpAmount(); //extra emp is... well full amount of normal hit
		
			engine.applyDamage(target, point, damageAmount, DamageType.ENERGY, empAmount, false, false, projectile.getSource());
                        engine.addHitParticle(point, particleVelocity, particleSize, particleBrightness, particleDuration, particleColor);
			//soundToPlay.playSound(soundName, pitch, volume, point, particleVelocity);
		}
	}	
}

Also, anyone able to take a look at my question earlier yet? http://fractalsoftworks.com/forum/index.php?topic=5061.msg85513#msg85513

Although i have knoticed the chain will arc to the fireing ship for some reason... odd

Modding / Re: Misc modding questions that are too minor to warrant their own thread

« on: January 22, 2013, 04:54:43 AM »

Regarding the spawnEmpArc() the notes say that you can target this to a specific location by passing in a custom class as the combatentity target: "@param empTargetEntity Target of the EMP arc. If it's a ship, it will randomly pick an engine nozzle/weapon to arc to. Can also pass in a custom class implementing CombatEntityAPI to visually target the EMP at a specific location (and not do any damage)."

Does anyone know a way to do this?

I was thinking allong the lines of useing addSmoothParticle(beam.getTo(), target.getVelocity(), 1f, 0f, .5f, CORE_COLOR); to create a teporary entity to target but couldnt get this to work >_<

Oh, another question. Is there a way to count how long a beam has been held onto a target? I want to make the chain lightning arc more times the longer a beam is held on a single target.

Guess i would need a way of makeing a global tag to check if the target is the same as the last and then if it is incrament the counter, if not reset it... no idea how to do that though? can we attatch infromation to the beam emmiter entity?

Okay, I think I got the infection system to a point where it's visually pleasing, though I still don't have a massive amount of separate graphics.



I added four 128x128 overlays, as well as three 64x64 overlays.

Oh man, i cant wait to see this in action. As for the infection beam, take a look at LazyWizards Chain lightning code get that beam to bounce

Do you call the script at: data.scripts.plugins.RotatingDish? Because thats where its package points at.

According to your error log, you call it at data/scripts/weapons/.

damnit, i missed the package data.scripts.weapons; Thanks Romeo_One

Hmm, quick tweak to LazyWizards code, Ancoring the arc to the emmiter looks much better so add the following lines to do so...
After the line of code "CombatEntityAPI currentVictim = target;" add this:

Code

CombatEntityAPI currentEmmiter = beam.getSource();	// Emmitter of the Next lightning chain is the target of this one

and change the "engine.spawnEmpArc" to:

Code

// Spawn this chain's lightning arc
engine.spawnEmpArc(beam.getSource(), source,
          currentEmmiter, currentVictim,
          DamageType.ENERGY, damage, emp, 100000f,
          "tachyon_lance_emp_impact", 15f,
          FRINGE_COLOR, CORE_COLOR);

currentEmmiter = currentVictim;	// Emmitter of the Next lightning chain is the target of this one

Just makes it look a bit nicer thats all.

Should look like this:

this will work for that. With a few tweaks, let me look at it for ya...

and done, well that was easy enough, just modified the awesome code from LazyWizard... Also changed the anchor point as it looked silly ancoring to the target... well i thought it did. Anyway:

Code

package data.scripts.weapons;

import com.fs.starfarer.api.combat.BeamAPI;
import com.fs.starfarer.api.combat.BeamEffectPlugin;
import com.fs.starfarer.api.combat.CombatEngineAPI;
import com.fs.starfarer.api.combat.CombatEntityAPI;
import com.fs.starfarer.api.combat.DamageType;
import com.fs.starfarer.api.combat.ShipAPI;
import com.fs.starfarer.api.util.IntervalUtil;
import java.awt.Color;
import java.util.*;
import org.lwjgl.util.vector.Vector2f;

public class LightningStrikeEffect implements BeamEffectPlugin
{
    private static final float TIME_BETWEEN_BURSTS = .1f;    // How long between each discharge
    private static final Color CORE_COLOR = new Color(255, 255, 255, 255);// What color is the core of the arc?
    private static final Color FRINGE_COLOR = new Color(85, 25, 215, 255);// What color is the fringe of the arc?
    private IntervalUtil fireInterval = new IntervalUtil(TIME_BETWEEN_BURSTS, TIME_BETWEEN_BURSTS);

    @Override //i have no idea what this does
    public void advance(float amount, CombatEngineAPI engine, BeamAPI beam)
    {
        CombatEntityAPI target = beam.getDamageTarget();
        // Check that we hit something, modified to arc to shields
        if (target != null && target instanceof ShipAPI)
        {
			//Only activate if beam is at full power (beam charge up time)
            if (beam.getBrightness() >= 1f)
            {
                fireInterval.advance(amount);
                if (fireInterval.intervalElapsed())
                {
                    // Source of the current lightning chain
                    Vector2f source = beam.getFrom();
                    // Victim of the current lightning chain
                    CombatEntityAPI currentVictim = target;
                    // Ensure we keep the same DPS as listed in the weapon's stats tooltip
                    float damage = beam.getWeapon().getDerivedStats().getDps()
                            * beam.getSource().getMutableStats().getBeamWeaponDamageMult().getModifiedValue()
                            * TIME_BETWEEN_BURSTS;
                    float emp = beam.getWeapon().getDerivedStats().getEmpPerSecond()
                            * TIME_BETWEEN_BURSTS;

					// Spawn lightning strike
                    engine.spawnEmpArc(beam.getSource(), source,
                                beam.getSource(), currentVictim,
                                DamageType.ENERGY, damage, emp, 100000f,
                                "tachyon_lance_emp_impact", 15f,
                                FRINGE_COLOR, CORE_COLOR);
                }
            }
        }
    }
}

BTW anyone know what does the "@overide" Does?

Just save the code I posted as ChainLightningEffect.java in the data/scripts/weapons/ folder. Then open the weapon file of the beam you want to use this effect and add this line:

Code

"beamEffect":"data.scripts.weapons.ChainLightningEffect",

would you beleve i had / instead of . in the effect refrence field >_< thank, i have no idea why i made that mistake.

Here's the code for a beam that creates a chain lightning effect. I tried to keep it easy to customize.

Thanks for the quick work there, however when i try to implement this i keep getting an obscure error, obviously im doing something wrong. Ive done a quick search but couldnt find a guide on how to add custom weapon effects to a mod, So i need to compile this to a class file and add it to the api Jar?

ah, so useing a function similar to the one psion did in his efffects?

Code

		List ships = engine.getAllShips();	
		Iterator it = ships.iterator();
			while (it.hasNext()) {
//* range checking here, pass inrantge ships into a Target vairable
}

Also it occours to me, to make a beamweapon with a lightning emp effect, couldnt we make an invisible beam weapon and give it the emp effect, but set the spawn point of the emp effect to the beam weapon emmitter? heck even haveing a faint beam that carrys the lightning would look cool. sort of like an ion beam that carrys the electric charge from your ship to the target so the lightning only shows when there is a valid target for the electricity to ground itself to (ie the beam hits something)... hmm, will have to check how to pull the emmiter location from the beam as that would look epic.

Edit: wait, is it as simple as beam.getFrom()? gona test this
