VR Blade Fight

My work:

● Gameplay design
● Implemented sound effects and audio
● Damage system, Block System and Heavy Attack function programming
● Background story creation

VR Blade fight can be briefly described as a face-to-face melee duel. We have always wanted to try to create a more immersive and interactive combat, and VR fits our needs perfectly. The whole demo can be divided into two parts: combat and exploration. The exploration part of the player can freely move, watch the surrounding scenery, get tips and move to enter the combat part. In the combat part, the player will fight against enemies in the scene.

Gameplay video

Full Gameplay V2.0

v1.0 is our first playable demo, the gameplay is relatively short and the environment setting is simple. In v2.0, we mainly added:

1. A practice battle in the beginning of the game. In this battle, the enemy will only carry out one kind of attack action, and both sides's attack will not cause damage except for heavy attack, players can practice how to parry.

2. Music and dialogs. We added a lot of different music throughout the game. Besides, there are dialogs we create to add a simple story to the game.

3. A nice environment and more space to explore. (Reference)

Combat system

In the combat, the enemy will randomly strike multiple attacks, and the attacks will also come from different directions. Players can use weapons to attack enemies or to block enemy attacks. The block system is shown in the left.

We created 8 collision box as the figure shown. The outer four collision box are tagged as "Large" and inner four are tagged as "Small". When the enemy perform an attack, for example, attack starts from player's right moving to player's left. Then the collision box at player's left side will be activated. Player will have to wave their weapon from left to right, collide with 2 collision box and then collide with enemy's weapon to block the attack.

The number of times the player block or parry enemy's attack are recorded. And it is related to the condition of performing a heavy attack.

Heavy Attack

Our game encourage players to block enemy's attack during the combat. So I designed and implemented"heavy attack" system. After 3 times the player blocks attack, the enemy will stay in "injured state" for 3 seconds. Player can attack the heart area (red area) to deal huge damage to enemy.

The heavy attack function is embed in our block function. After the third time player parries attack, which is 'block.blockNum == 3', the enemy will enter the 'Injured state'. We have a independent timer to count the time.

Both condition, a heavy attack or the end of time will cause the enemy to exit the injured state and clear the blocks number.

Recovery

In order to make the game more difficult and interesting, we designed a recovery action for the final boss. As can be seen in the gif above, when the enemy's health drops below 50%, the enemy makes a roar, which will restore part of his health.

Damage Control

We controlled all the damage with a script. By attaching scripts to weapons in unity, you can easily adjust the damage done by different characters and heavy attacks in unity. The judgment of whether the player has hit a heavy attack is also in the script.
