Throw Object — Tons of Customizable Parameters

Input sensitivity, force, torque, delays, position, rotation, fading, etc.:
— For all Throwing Objects at once;
— For each Throwing Objects individually.

10 customized Throwing Objects

• Weapons: Axe, Sword, Broken Sword,
• Balls: Basketball, Brick Ball (Grey), Brick Ball (Red);
• Miscellaneous: Coin, Shovel, Horseshoe, Tree (branch).

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;
• Paper Bin AR;
• FPS with Throwing Objects;
• AR, VR games with Throwing Objects;
• Survival Game;
• Any of your Bold Fantasies.

Modes

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

The system completely works on desktop as well as on mobiles: you can throw object with the mouse or with a finger.

Click Or Tap

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

FPS

For the FPS game, there is an option for fixing the input position in a specific place on the screen (by default in the center of the screen). Desktop Demo uses CharacterController (Throw force takes into account the speed of the player’s movement).

Flick

In this mode, you can throw object in the style of the 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 the Speed of the Throwing Object.

Scripts

Throwing System consists of 3 control scripts.

RandomObjectPooler.cs — Object Pool

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

ThrowControl.cs

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.

Events

• Next Events have ThrowingObject as a parameter. So you have more flexibility with access to instances of ThrowingObject.cs in outer functions assigned to Events.
  • OnThrow,
  • OnNextThrowGetting,
  • OnReset,
  • OnFadingOut,
• OnInitialized.

Coroutines

The only script that uses coroutine calls.

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

ThrowingObject.cs

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

• 

• 

Events

• OnThrow;
• OnResetPhysicsBase.

Custom Data

• Mono Behaviour Custom: it is useful to assign a specific control script for a unique type of Throwing Object and access to it outside the Throwing System. Example: BasketballBallControl.cs in AR Basketball GO (docs) & Basketball Game (docs).
• Flag Custom: for Any User Logic outside the Throwing System.

Colliders

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.
Unity Package contains some examples with Custom Center of Mass.

There is no magic function that calculates the 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 the 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.

Fading (Dissolving) VFX

It’s Separate Independent Script for Throwing Objects: MaterialControl.cs (It’s used by ThrowingObject.cs). You can use it for Fading outside Throwing System (Examples: Ring, Ring Holder, Net, Backboard, Pole in AR Basketball GO (docs) & Basketball Game (docs)).

Here you can control Fading In & Fading Out with Full Control of Value, Delay, Time & Speed for Indicated Shader Parameter.

Shaders

There are 3 Custom Shaders with Shadow Fading & “Slice Guide” Texture for Fading (Your Material > Shader > Custom > Makaka Games):

• Diffuse (Dissolving),
• Bumped Diffuse (Dissolving),
• Particles Cutout Transparent — for Transparent Textures (Example: Net in AR Basketball GO (docs) & Basketball Game (docs)).

Tutorial

This tutorial is relevant for 4.3+ version of Asset.
Tutorials for previous versions can be found in the asset folder.

Getting Started with Throw Object 3D

Folders in the package by Default:

• Makaka Games.

Steps

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 2021.1.12.
2. Build Settings > iOS, Android, Standalone (PC, Mac) or WebGL > Switch Platform.
3. Download and import Throw Object 3D into Unity.
   1. Warning Windows:
      1. Click “Import” to overwrite the Project Settings with predefined ones.
      2. Click “Install/Upgrade” for Package Manager Dependencies.
4. Next Packages are provided with Unity Package Manager, and they are already installed for this Asset by default. If packages are missing (Warning Window did not appear) then install them again with Unity Package Manager (with advanced settings enabled: “Pre-release Packages” & “Show Dependencies”):
   1. TextMesh Pro 3.0.6:
      1. Always Required: Window > TextMeshPro > Import TMP Essential Resources.
5. Reopen Unity Project.
6. Open Scene: Makaka Games > Throw Object 3D > Scenes > Demo.
7. Test In Unity Editor or Build for Mobile or Desktop.

Object Count

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

Creating 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. Customize Material & its Fading (see “Fading” chapter) in Mesh Renderer component (Duplicate Material in Project View and indicate here to separate different Throwing Objects),
   3. Customize Colliders:
      1. Indicate Mesh in Mesh Collider component (or in more suitable collider component);
   4. Option: Customize the Center of Mass for more natural Throwing;
3. Customize the Transform component as you wish;
4. Apply Changes to Prefab;
5. Delete Game Object from Scene;
6. Option: Add Asset Label for Prefab to convenient searching in Project View;
7. Add Prefab to RandomObjectPooler component of ThrowingPoolControl Game Object;
8. Throw Object Forward in “Play Mode”.

Change Spawn Position of Throwing Objects

See the “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”.

Change the Color of Throwing Objects in Runtime

SetMaterial() function is used instead of SetColor() functions all over the system to avoid memory allocations.

So if you plan to change Colors of Throwing Objects in Runtime outside Throwing System you need to create Materials with Target colors in advance.

Example: Red Fail Material in AR Basketball GO (docs) & Basketball Game (docs).
