接着昨天的教程，我们给载具加上一些特殊功能
1.改变载具的声效声音事件教程：
我们把载具的声效.ogg文件进行上面教程的操作，然后将载具的声效进行替换：
在我们的载具类HeisenCarEntity.java中添加：
//飞奔的音效
protected void playGallopSound(SoundType p_190680_1_) {
super.playGallopSound(p_190680_1_);
// if (this.random.nextInt(2) > -1) {
//我们自定义的音效
this.playSound(SoundInit.ENTITY_HEISENCAR_ROLLING.get(), p_190680_1_.getVolume() * 0.6F, p_190680_1_.getPitch());
// }
ItemStack stack = this.inventory.getItem(1);
if (isArmor(stack)) stack.onHorseArmorTick(level, this);
}
//挂机音效
protected SoundEvent getAmbientSound() {
super.getAmbientSound();
return SoundInit.ENTITY_HEISENCAR_ROLLING.get();
}
//载具爆炸损毁音效
protected SoundEvent getDeathSound() {
super.getDeathSound();
return SoundInit.ENTITY_HEISENCAR_FIRING.get();
}
//载具愤怒音效
protected SoundEvent getAngrySound() {
super.getAngrySound();
return SoundInit.ENTITY_HEISENCAR_ROLLING.get();
}
//载具加油音效
@Nullable
protected SoundEvent getEatingSound() {
return SoundInit.ENTITY_HEISENCAR_ROLLING.get();
}
//载具遭到破坏音效
protected SoundEvent getHurtSound(DamageSource p_184601_1_) {
super.getHurtSound(p_184601_1_);
return SoundInit.ENTITY_HEISENCAR_ROLLING.get();
}
//载具运动音效
protected void playStepSound(BlockPos p_180429_1_, BlockState p_180429_2_) {
if (!p_180429_2_.getMaterial().isLiquid()) {
BlockState blockstate = this.level.getBlockState(p_180429_1_.above());
SoundType soundtype = p_180429_2_.getSoundType(level, p_180429_1_, this);
if (blockstate.is(Blocks.SNOW)) {
soundtype = blockstate.getSoundType(level, p_180429_1_, this);
}
if (this.isVehicle() && this.canGallop) {
++this.gallopSoundCounter;
if (this.gallopSoundCounter > 5 && this.gallopSoundCounter % 3 == 0) {
this.playGallopSound(soundtype);
} else if (this.gallopSoundCounter <= 5) {
this.playSound(SoundInit.ENTITY_HEISENCAR_ROLLING.get(), soundtype.getVolume() * 0.15F, soundtype.getPitch());
}
} else if (soundtype == SoundType.WOOD) {
this.playSound(SoundInit.ENTITY_HEISENCAR_ROLLING.get(), soundtype.getVolume() * 0.15F, soundtype.getPitch());
} else {
this.playSound(SoundInit.ENTITY_HEISENCAR_ROLLING.get(), soundtype.getVolume() * 0.15F, soundtype.getPitch());
}
}
}
//载具摔落音效
public boolean causeFallDamage(float p_225503_1_, float p_225503_2_) {
if (p_225503_1_ > 1.0F) {
this.playSound(SoundInit.ENTITY_HEISENCAR_ROLLING.get(), 0.4F, 1.0F);
}
int i = this.calculateFallDamage(p_225503_1_, p_225503_2_);
if (i <= 0) {
return false;
} else {
this.hurt(DamageSource.FALL, (float)i);
if (this.isVehicle()) {
for(Entity entity : this.getIndirectPassengers()) {
entity.hurt(DamageSource.FALL, (float)i);
}
}
this.playBlockFallSound();
return true;
}
}
//载具腾跃音效
protected void playJumpSound() {
this.playSound(SoundInit.ENTITY_HEISENCAR_FIRING.get(), 0.4F, 1.0F);
}
2.增加载具冲撞伤害
在载具类HeisenCarEntity.java添加hurt函数：
private void hurt(List<Entity> p_70971_1_) {
for(Entity entity : p_70971_1_) {
if (entity instanceof LivingEntity) {
if(!(entity instanceof PlayerEntity)) {
//伤害数值可自定义
entity.hurt(DamageSource.mobAttack(this), 8.0F);
this.doEnchantDamageEffects(this, entity);
if(random.nextInt(10)>8)
{
this.heal(random.nextFloat()*2);
}
}
}
}
}
在aiStep()函数中添加hurt的函数调用：
public void aiStep() {
super.aiStep();
this.hurt(this.level.getEntities(this, this.getBoundingBox().inflate(1.0D), EntityPredicates.NO_CREATIVE_OR_SPECTATOR));
}
3.增加载具随机爆破效果
我们默认进入载具后按空格(Space)进行随机爆破效果
在travel()函数中添加如下语句
if(this.isJumping){
this.addEffect(new EffectInstance(Effects.DAMAGE_BOOST, 20, 1,true,true));
this.addEffect(new EffectInstance(Effects.MOVEMENT_SPEED, 20, 1,true,true));
this.addEffect(new EffectInstance(Effects.HEAL, 20, 3));
//爆炸效果设定 爆炸的坐标 X,Y,Z，爆炸威力，是否破坏方块
this.level.explode((Entity)null, this.getX()+1+random.nextInt(2), this.getY()+1.5, this.getZ()+1+random.nextInt(2), (float)1, true, Explosion.Mode.NONE);
}
4.增加载具开火效果子弹教程：
我们默认进入载具后按空格(Space)进行设计效果
在travel()函数中添加如下语句
//你要召唤的子弹类型
EntityM1851B abstractarrowentity = new EntityM1851B(this.level,livingentity);
//子弹的射击坐标，初速度
abstractarrowentity.shootFromRotation(livingentity, livingentity.xRot, livingentity.yRot, 0.0F, f * 25.0F, 1.0F);
abstractarrowentity.level.addParticle(ParticleTypes.FLAME, abstractarrowentity.getX(), abstractarrowentity.getY(), abstractarrowentity.getZ(), abstractarrowentity.position().x , abstractarrowentity.position().y, abstractarrowentity.position().z);
abstractarrowentity.playSound(SoundInit.M1851.get(), 2.0F,2.0F);
5.增加撞飞效果
我们基于第二步，在hurt函数中加入对被撞击物体的坐标极其位移的设定，就完成了对生物的撞飞效果：
private void hurt(List<Entity> p_70971_1_) {
for(Entity entity : p_70971_1_) {
if (entity instanceof LivingEntity) {
if(!(entity instanceof PlayerEntity)) {
//撞击伤害
entity.hurt(DamageSource.mobAttack(this), 8.0F);
this.doEnchantDamageEffects(this, entity);
//撞飞效果 d0,d1...d4等参数均为获取载具与被撞物体间的距离关系，一般不改
double d0 = (this.getBoundingBox().minX + this.getBoundingBox().maxX) / 2.0D;
double d1 = (this.getBoundingBox().minZ + this.getBoundingBox().maxZ) / 2.0D;
double d2 = entity.getX() - d0;
double d3 = entity.getZ() - d1;
double d4 = Math.max(d2 * d2 + d3 * d3, 0.1D);
//这3个参数为x轴，y轴，z轴的撞飞距离，可自行调节
entity.push(d2 / d4 * 4.0D, (double)0.5F+random.nextDouble(), d3 / d4 * 4.0D);
}
}
}
}
6.进入游戏测试：
Perfect！
