So much simpler than i thought thanks!

Can anybody tell me how to make custom achievements in forge 1.10.2. Also could you include how to trigger them when you craft a certain item. Thanks in advance.

This is mod that, as its name suggests, adds crossbows into the game. In total 15 new crossbows have been added and 9 bolts have also been added. For full information please visit my project page: https://minecraft.curseforge.com/projects/crossbows-mod?gameCategorySlug=mc-mods&projectID=249018 Also any suggestions/requests are greatly appreciated.

This is my code for all the items: The Bow class: package com.cameron.crossbowmod.items; import net.minecraft.creativetab.CreativeTabs; import net.minecraft.item.ItemBow; public class WoodCrossbow extends ItemBow { public WoodCrossbow() { this.setMaxDamage(20);

RenderingRegistry.registerEntityRenderingHandler(EntityWoodBolt.class, new RenderWoodBolt());

Also i just noticed that the Rendering registery has been deprecated is their a new method for 1.10?

Yeah i copied them directly, do you want to see my code?

I have been through all of those and the render arrow class as well, however when i have tried to copy them it just doesn't seem to work. I cannot get the animation for the bow to work nor can i see any of the custom arrows.

I am very new to modding and was wondering if anyone could help me with creating a custom bow that shoots custom arrows. I have not been able to find any 1.10.2 tutorials for this and got myself stuck after trying everything on my own. Any help/advice is greatly appreciated.

I am struggling to figure out why when i shoot my custom arrow it seems to collide with my player and ends up rotating so that it is side on when it collides with a block.
