Right now, there should be an issue between the grenades and the guns because the grenades will operate differently. They don’t have a fire animation so they basically loop. Let’s adjust this so weapons that fire bullets animate differently.

Let’s build a animation for the pistol. This will occur under the fireWeapon function and this class should be built to encompass all classes. To start, let’s work on the pistol by adding in a muzzle flash, bullet case ejection, and smoke from filebase.

We need to set our game up so that our character does the correct aiming animations when we select our weapon. Currently, it only does the pistol aim for the grenade and the assault rifle. To do this, we need to first change the firing of the blend tree.

Of course, you will want to switch the weapons of your character but not all characters have the same idle state depending on the weapon held. Let’s transition between these states and use the inputs 1–3 to swap weapons.

More often than not, you want to add weapon to your character and it should be simple. Every weapon is different so you should plan on your position for each weapon to be the same — everything else underneath can be different.

One way to do a crouch is to create a layer called crouch and an avatar named crouch. We can exclude the legs and ik, the rest stays on and we can test the character crouching and then when moving, it retains the step placement as well. It looks like…

There may not be an animation available, but we’re going to aim up and down by copying animations

In our scenario, our legs actually stay still when aiming down the sights. What we want to do is carry over our lower body movements while keeping our aim established. To do that, we need to create a layer mask. In our layer, create a new layer called aiming. Delete the old aiming animation.

To aim a gun, we need to use cinemachine to go to a OTS view. We also need to use layer masks. Start by creating a new virtual camera and place it in the ots perspective.
