MiniPhysics-By-38A
A tiny physical engine made by 5438A38A in VB6 and ported into C++ with Qt and improved by Wohlstand
This engine demo implements a classical platform game physics. Such a:
- Rectangular blocks of any size
- Truangular slope blocks of any size (floor and ceiling). Auto-align character's Y position at top corner of slope while walking up on it.
- Speed-adding stack (adding speed to objects staying on moving other)
- Collision filters to block character movement at one of sides and pass character at others
- Overlapping detection (character will be painted red) when player is touches inside boundaries area of the solid blocks
- Crush detection when two moving solid boxes will crush at top and bottom, or at left and right
- Cliff detection when character is about edge, on both rectanglar and trianglar blocks
- Touched blocks detection to process special actions from touching of the special blocks (for example, hurt player or NPC on touching a danger surfaces)

Working demo for Win32 can be got here
Controlling character
- Arrow keys (Move left-right)
- Space (jump)
- F1...F4 (toggle loop delay: F1 = 25 milliseconds between each frame, F2 = 100, F3 = 250, F4 = 500)
- 1, 2, 3 (toggle character's size: 1 = 24x30 (small playable character / ducked state), 2 = 32x32 (most regular NPC/item), 3 = 24x50 (regular playable character size))
- Q (disable/enable ability to walk over floor holes. In SMBX playable characters are can that. NPC-s can't)
- W (disable/enable automatic aligning Y on slope top corner while walking up on slope. Disabled in the sliding mode).
- F11 toggle demo level 1 (toggling while already switched just returns character to initial position)
- F12 toggle demo level 2 (toggling while already switched just returns character to initial position)
Notes: Character automatically will be teleported to up side of screen when it will fall down into the pit
Building from sources
- Clonning requires a downloading of dependent submodules
git clone https://github.com/Wohlhabend-Networks/MiniPhysics-By-38A.git
cd MiniPhysics-By-38A
git submodule update --init --recursive- This demo can be built on almost any platform supported by Qt (Linux, Windows, Mac OS X).
- For correct working OpenGL support is required.
- You are required to have latest Qt 5 package which you can take here Just open the MiniPhysics.pro in the Qt Creator and process the build.
