[Tameet]

I want to change grass drops, but i'm absolutely noob in minecraft modding. I can just create new custom items using different tutorials. How i can do it?

Subscribe to a HarvestDropsEvent, then add/remove the drops from the drops list provided to you by HarvestDropsEvent#getDrops.

Should i type HarvesDropsEvent#getDrops into void HarvestDropsEvent event? (Sorry if i look like a stupid noob)

No idea what this is supposed to mean. It highly suggests you lack the necessary basic Java knowledge required for modding.

i did it, but i don't know how to change the drop chance
 

@SubscribeEvent
	public void HarvestDropsEvent(HarvestDropsEvent event) {
		if ((event.getState().getBlock() == Blocks.GRASS)) {
			event.getDrops().add(new ItemStack(ItemList.fiber, 1));
		}
	}

Use random numbers to add more or less of the drops.

It's working, thanks for help

@SubscribeEvent
	public void HarvestDropsEvent(HarvestDropsEvent event) {
		if ((event.getState().getBlock() == Blocks.GRASS && event.getWorld().getRandom().nextInt(2) == 0)) {
			event.getDrops().add(new ItemStack(ItemList.fiber, 1));
		}
	}
