BATTLE IO — Character attack in depth

This is the guide for Battle IO game template which selling at Unity Asset Store (https://www.assetstore.unity3d.com/#!/content/101113?aid=1100lGeN)

If you are already read How to add new weapon item, In that part you will see about WeaponData which contains Action Id, Animation Duration and Launch Duration that you may doubt how it working.


About Action Id we use it to determine which animation will play when attacking, you should set it relates to condition in CharacterAnimator which located at BattleIO/Demo/Animations

You can open it to add new Animation for this example I will show how I adding Spear attack animation

When you opened CharacterAnimator you will see tab like this

Then select Top layer because all attack animation have been set on that layer

Select Top layer, then you will see Attack sub-state machine

Double click on Attack sub-state machine you will see how transition work to play attack animation

You can click on arrow line to see condition to play animation

Select any arrow line
See conditions in Inspector

Then I will add new attack animation named Atk-Spear

Right click on space in Animator tab then select Create State -> Empty

Then select new created State set it name to Atk-Spear and set its animation clip (Caution: Attack animation clip should not be loop)

Then make transition from Any State to Atk-Spear and set its conditions

As above settings, I set Can Transition To Self as False because I don’t want it playing attack animation while last attack animation is not finish

Conditions DoAction is required to make it start playing attack animation it have been defined by codes (CharacterEntity.cs), ActionID equals to 2 to make condition to play this animation when equip weapon with its Action Id data equals to 2

Then make transition from Atk-Spear to Up and select NonAttack state machine

Then set conditions for this transition to stop playing this animation when DoAction equals to False

Then set Action Id in item data which you want to make it play this animation to 2


Next is about Animation Duration and Launch Duration

For Animation Duration setting we have to see duration of the animation it’s easy just see it in Animation Clip

Then we’re going to find which duration is the frame attack character should launch damage entity, I’d recommend you to create new scene (File ->New Scene)

Then drag any character model (BattleIO/Demo/Prefabs/CharacterModel) to the scene and then open Animation tab via menu Window -> Animation

Select the character then in Animation tab select AttackSpear clip

Then select frame which you want to launch damage entity

In this example selected frame is 10 of 18, then use Animation Duration with this to find Launch Duration

Let’s 10 is which percent of 18, it’s easy 10 / 18 * 100 = 55, so it’s 55 %

Then use this percent to find Launch Duration, When Animation Duration equals to 0.79, 0.79 * 55 / 100 = 0.4345, so this is amount of Launch Duration

If you want to increase speed for animation clip you have to change number of Samples then find Animation Duration and Launch Duration again

The number of Samples
