TiBox2d

A Taichi Hackthon project
Yet another game-oriented GPU Physics Engine

Motivation:

  1. Fulfill a wish from 2 years ago when I first learned Taichi and GAMES201 完成一个鸽了许久的承诺
  2. Most developers who want to write a physics simulation game with Taichi can't help but use "MPM99" as a template and modify it, so it's time to bring some diversity. 写游戏竟然不用PBD？
  3. for fun 确实很好玩

API与使用方法

故事开始

import TiBox2d
import taichi as ti

创建Tibox2d物理收集器

tibox_collector = TiBox2d.Collector()

使用收集器收集你想模拟的物理材料，输入它AABB左下和右上的位置坐标

tibox_collector.add_water_box(5.0, 5.0, 15.0, 15.0)
tibox_collector.add_plastic_box(16.0, 20.0, 26.0, 30.0)
tibox_collector.add_rigid_box(27.0, 35.0, 37.0, 45.0)
tibox_collector.add_elastic_box(38.0, 50.0, 48.0, 60.0)
tibox_collector.add_rope(50.0, 0.0, 30.0)

创建求解器并编译

tibox_solver = TiBox2d.Solver(...)
tibox_solver.Compile(tibox_collector)

在主循环中调用step进行模拟

tibox_solver = TiBox2d.Solver(...)
tibox_solver.step(tibox_collector)

这时位置就会在tibox_solver.positions中得到更新
