Package is a Part of Unity Assets

  1. Basketball Game (docs).

  • OnFadeOut,
  • OnInitialized.

Throw Object — Tons of Customizable Parameters

Input sensitivity, force, torque, delays, position, rotation, etc.

  • For all Throwing Objects at once,
  • For each Throwing Objects individually.

19 customized Throwing Objects

6 Demos

  • 2 FPS Demos integrated with FPSController from Standard Assets by Unity Technologies (Desktop):
    • Throw force takes into account the speed of the player’s movement;
  • 4 Demos with a static position of the player in “Flick” & “Click Or Tap” modes (Mobile & Desktop).

Use Cases

  • A game in the style of Pokemon GO (iOS, Android),
  • A game in the style of Can Knockdown (iOS, Android),
  • Paper Toss Boss (iOS, Android);
  • Paper Bin AR (iOS);
  • FPS with Throwing Objects;
  • AR, VR games with Throwing Objects;
  • Survival Game;
  • Any of your Bold Fantasies.


The higher click (or tap) position on the screen, the greater the strength of the throw.

System completely works on desktop as well as on mobiles: you can throw object with mouse or with finger.

Click Or Tap

In this mode, game object is throwing in the direction of the click (desktop) or tap (mobile).


For FPS game there is an option for fixing input position in a specific place on the screen (by default in the center of the screen).


In this mode, you can throw object in the style of Pokemon GO game (iOS, Android) (by flicking it from the bottom of the screen up toward the target).

Is Full Path For Flick?

If it’s false then it allows fast flicks only: positions in the last and previous frames are taken into account.

Dynamic Sound System

Sound depends on Speed of Throwing Object.


Throwing system consists of three control scripts.

Throwing Object

The script contains basic functions and parameters to operate Throwing Object.
This script must be attached to each Throwing Prefab (check tutorial).

Throw Control

This is the main script that manages throw & all Throwing Objects on a scene through Object Pool.
The script uses disabling and enabling the following nodes: Colliders, Triggers, Renderers.

Work Scheme:

  1. Initialize Object Pool,
  2. Initialize Throwing Objects,
  3. Get the First Throw,
  4. Get Next Throw.


The only script that uses coroutines calls.

Because of coroutines behavior, it is impossible to place some methods inside Throwing Object script.
OOP does not work in this case, but we have a stable throwing with Object Pool.

Object Pool (Random Object Pooler)

Object Pool is performance optimization technique through Objects Reusing. All Throwing Objects are created on start and used throughout the game session.


Rotation (Torque) & Center of Mass

There are some nuances with Rigidbody.centerOfMass when rotation.

Symmetric Mesh

If you use Mesh Collider for Throwing Game Object and your mesh is ideally symmetric then it is the perfect case and game object will throw naturally.

Asymmetric Mesh

If you use Mesh Collider for Throwing Game Object and your mesh is asymmetric then you will have unnatural throw behavior when rotation.

Solution 1: Custom Center of Mass

You can indicate Custom Center of Mass manually in the Editor.
Package contains some examples with Custom Center of Mass.

There is no magic function which calculates right Center of Mass.

Solution 2: Simple forms of colliders

You need to use one or more simple forms of colliders (box, sphere, etc.) placing them on the same Throwing Game Object and along the straight line. So in this case, we have a right center of mass & right rotation.

Convex Mesh

Unity allows you to use only convex mesh colliders. In some cases, it is not what you need because the collider covers more space, than the object itself in some points.

In order to quickly & automatically get a convex mesh collider for complex objects, use Technie Collider Creator.


Getting Started with Throw Object 3D

For legal reasons, I can’t include some assets in the package, but you can get them for free separately.

Folders in the package by Default:


If you have any issues with the first launch then just Reach Support with Invoice Number and Get Help.

If you read this tutorial from PDF, first check the latest docs online to get actual information.

  1. Create New Unity Project with Unity 2019.1.3.
  2. Download and import Throw Object 3D into Unity.
  3. Option — Download and import 3rd-Party Assets:
  4. Reopen Unity project;
  5. Test in the Unity Editor;
  6. Build for Mobile or Desktop.

How to set objects count?

  1. Hierarchy View > “ThrowingPoolControl” Game Object.
  2. Inspector View > “Random Object Pooler” script > “Init Pooled Amount” Parameter.

How to create your own Throwing Object Prefab?

  1. Create Prefab with a template:
    1. Drag one of the customized throwing prefabs into the scene,
    2. Name your Game Object,
    3. Drag named Game Object into Project View to create your own Prefab;
  2. Select Game Object on the Scene & Customize it:
    1. Indicate Mesh in Mesh Filter component,
    2. Indicate Material in Mesh Renderer component,
    3. Customize Colliders:
      1. Indicate Mesh in Mesh Collider component (or in more suitable collider component);
    4. Option: Customize Center of Mass for more natural Throwing;
  3. Customize the Transform component as you wish;
  4. Option: Customize Fade Out (see below);
  5. Apply Changes to Prefab;
  6. Delete Game Object from Scene;
  7. Option: Add Asset Label for Prefab to convenient searching in Project View;
  8. Add Prefab to Random Object Pooler;
  9. Throw Object Forward in “Play Mode”.

Option: Fade Out Customizing

  1. Change Shader of Material to Shader with the Main Color property (e.g. Legacy Shaders > Bumped Diffuse);
  2. Duplicate Material in the Project View and name it (i.e [MaterialName]_FadeOut);
  3. Change Shader of Duplicated Material:
    • [Standard]: Rendering Mode > Fade;
    • [Legacy]: to shader from the Transparent Shader Family (e.g. Legacy Shaders > Transparent > Bumped Diffuse);
  4. Indicate both materials in the Fade Out Section of Throwing Objects Script in Throwing Prefab.

How to change Spawn Position of Throwing Objects?

See “Position” section in the Editor of ThrowingObject.cs for each Throwing Prefab individually.

  • [X, Y]: “Position In Viewport On Reset”,
  • [Z]: “Camera Near Clip Plane Factor On Reset”.
