Physics Forces

Test using TCastleRigidBody.AddForce and friends.

A number of rigid bodies are placed in a closed box (because we will hit them with forces and we don't want to escape).

The blue arrow represents the force position, direction, strength.

• Move it by AWSD
• Scale by QE
• Rotate by ZC

Press (you can press once, or hold the key down to keep applying):

• Key 7: TCastleRigidBody.AddForceAtPosition
• Key 8: TCastleRigidBody.AddForce
• Key 9: TCastleRigidBody.AddTorque
• Key 0: TCastleRigidBody.ApplyImpulse

The idea is that you can play this weird game with both hands. Left hand controls the arrow (force position/direction), right hand makes given force active.

Using Castle Game Engine.

Building

Compile by:

• CGE editor. Just use menu items "Compile" or "Compile And Run".

• Or use CGE command-line build tool. Run castle-engine compile in this directory.

• Or use Lazarus. Open in Lazarus physics_forces_standalone.lpi file and compile / run from Lazarus. Make sure to first register CGE Lazarus packages.

• Or use Delphi. Open in Delphi physics_forces_standalone.dproj file and compile / run from Delphi. See CGE and Delphi documentation for details.
