🦾Procedural

​

Tac Procedural Animation

This component is responsible for all procedural animation features in the pack, specifically:

• Weapon sway
• Aiming
• Weapon and hands positioning
• Movement animations and recoil
• Spine rotation
• Pistol quick draw mechanic

• Aiming Weight: influence procedural aiming; if set to 1 - aiming will be fully applied, 0 - disabled completely.
• Pitch Input: look up angle.
• Yaw Input: look right/left angle.

The Bones struct contains references to skeleton bone transforms:

• Look Up/Right Bones: contains spine bones to look up/right.

How to use it in code

The integration process involves updating input values of this component. We will use the TacticalShooterPlayer script as an example.

​

Initialization

Add a new field of the TacticalProceduralAnimation type, and then initialize it on Start. The component does not require manual initialization, as it handles it under the hood.

​

Aiming

To make procedural aiming work, it’s essential to update aimingWeight and aimPoint: The aimingWeight is a value in range [0;1], make sure to smoothly interpolate it to 1 when aiming, and to zero when not. It’s also important to provide the aimTransform - a KTransform (position & rotation) pose that represents aim point relative to the weapon transform. Here’s an example of how this value is computed in the pack:

​

Equipping a new weapon

TacticalProceduralAnimation component uses TacticalWeaponSettings (a Scriptable Object) as a data source. It is important to update these settings when a new weapon is equipped:

​

Updating Inputs

To make the player look around and sway the weapon, make sure to update aim and move inputs:

​

Pistol quick draw mechanic

In Tactical Shooter Pack, you can quick-draw a sideram while holding a rifle. The mechanic relies on the pistol (siderarm) pose relative to the right hand. To update such a pose, it’s important to use this method: The gunRightHandPose field is a part of the TacticalShooterWeapon component: When the game starts, every weapon will sample a base idle pose to compute the weapon pose relative to the right hand.

Playing IK Motions

IK Motion is a feature that allows you to play custom additive IK motions at runtime:

• Rotation/Translation Curves: define motion for each translation and rotation axes.
• Rotation/Translation Scale: multipliers for each translation and rotation axes.
• Blend Time: blending in time in seconds.
• Play Rate: playback multiplier.
