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)

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.
