Pushback

Pushback

This resource is used in Reaction-Lists to apply pushback to opponents when an attack connects. Before diving into the structure and functionality of pushback, here are some key concepts to understand:

Pushback Overview

A pushback is divided into two distinct phases:

  1. Non-linear Phase

    • This occurs at the start of the pushback.
    • Refers to the Pushback Extradata resource
    • The amount of pushback applied on each frame differs (generally decreasing overtime).
    • Example:
      • Frame 1: 100 units
      • Frame 2: 50 units
      • Frame 3: 25 units
      • ...and so on

  2. Linear Phase

    • This follows the non-linear phase.
    • Pushback is applied at a constant rate per frame.

This structure consists of:

  • Linear Displacement: Duration
  • Linear Displacement: Units (how much distance is covered per frame)
  • Number of non-linear Pushback Items (Pushback Extradata)
  • Non-linear Pushback Items (Pushback Extradata)

Example

Let's take an example Pushback item from Nina's moveset

Linear Duration: 44
Linear Displacement: 60
Num of non-linear Pushback Items: 8
non-linear Pushback Items: [132, 61, 30, 15, 10, 0, 0, 0]
  • This has 8 frames of non-linear pushbacks (Pushback Extradata) where first frame will have 132 units of displacement, second will be 61, third will 15, fourth will be 10 and the rest will be 0.
  • After the first 8 frames, over the course of next 44 frames, a linear displacement of 60 will be applied.

Structure

All Games (Post-Tekken 5) 
struct tk_pushback
{
  uint16_t duration; // Linear
  int16_t displacement; // Linear (can be +ve or -ve)
  uint32_t num_of_pushback_extradatas; // How many non-linear frames
  tk_pushback_extradata *pushback_extradata; // Array of non-linear displacements
};
