[1.16.1] Summon any entity using event trigger

[Geornamezi]

Hello, I am trying to make event, that triggers when I attack any mob and it will summon primed tnt and it will instantly blow up.

What was always working was that I placed block under that entity.

My code for placing blocks under entity:

@Mod.EventBusSubscriber(modid = Geornamezi.MOD_ID, bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT)
public class ModClientEvents {

    @SubscribeEvent
    public static void attackEntity(AttackEntityEvent event) {
        if (event.getEntityLiving().getHeldItemMainhand().getItem() == RegistryHandler.GEORNAMEZI.get()) {
        	if (event.getTarget().isAlive()) {
            	LivingEntity target = (LivingEntity) event.getTarget();
            	if (target instanceof Entity) {
            
           	 	World world = target.getEntityWorld();
            		world.setBlockState(target.getPosition().add(0, -1, 0), RegistryHandler.GEORNAMEZI_BLOCK.get().getDefaultState());
         }
     }
}}  

I seen that there is world.createExplosion(), but i dont know, how to get things working inside that brackets.

Important thing is that, I am using using Forge 1.16.1 32.0.63 with mappings from July 7, 2020 (because i dont know, how to code with newer and mapped mappings).

Thank you for any post on this theme.

George
