Characters' movement

• To simulate the movements of a classic Beat'em Up game, we decided to constaint the movement to only left and right for the 2D part of the level, and then left/right and up/down

• Characters will always face the camera, especially the 2D character to avoid any visual oddities

• The jump works the same as Beat'em Up and Fighting games ; there is no air control. The directional input will control if the character goes straight or in a direction

Characters' attacks

• Each character has the same amount of attacks :

  • A 3 hit combo

  • A special attack

  • An air attack

  • And a special air attack

• Here, we have the same base for both 3 hit combos and air attacks, but the special attacks are different for each character.

  • For the ground special attack : The 2D character has a dash that deals damage at the end, while the 3D one does an attack that makes him jump.

  • For the air special attack, both launch a projectile. The 2D character will launch it in a straight vertical line in front of her ; the 3D character launch it in a diagonal line.

• In terms of functionality, attacks are actors that follows the same order of Startup, Active and Recovery frames based on the attack animation.

• There is a cancel system that allows some attacks to end sooner to make a new one ; the 3 hit combo is  working with this system, and each of these 3 attacks can be canceled into the ground special attack.

Animation Integration

• As the project has a 3D and a 2D character, two methods has been used

• For the 3D character, a simple Animation Blueprint was created, following the movement state of the character (Idle, Walking, Jumping) and the current attack

• For the 2D character, as there is no Animation Blueprint to work with 2D Paper Flipbooks, a function was made to select which flipbook has to be played in each situation
