Detailed Description

This class exposes parameters specific to odedynam as an implementation of iDynamics.

In most cases SystemState should not be modified directly unless you want the behavior of a specific system different from others.

virtual void iODEDynamicSystemState::EnableFastObjects bool    enable [pure virtual]
 

The following enables special robustness checks for fast moving objects to determine if they will tunneling and adjusts the physics frame resolution (rate) to a double for that step (possible doing this recursively down to a potentially infinite resolution for a given step, depending on the speed of the objects being tested) Only enable this if you are experiencing tunneling problems and can't afford to increase the standard FrameRate in the settings above Setting this in iODEDynamicState will set it for each System Use this only if you want a specific system to behave differently.

virtual void iODEDynamicSystemState::EnableFrameRate bool    enable [pure virtual]
 

NOTE: This should not be done here if its been done in iODEDynamicState The following code enables a constant framerate on processing this means if you set the frame rate to (default) 50 The stepsize passed into Step is treated as the elapsed time in seconds received from the virtual clock GetElapsedTicks.

The physics will iterate a number of steps at 1/50th of a second until enough time has passed to account for the time Beware the default setting for frame limit is 10, which means if the stepsize passed to Step is longer than 1/10 a second the physics will stop iterating and slow down. Never set this parameter to 0 or else you could incur cycle of death where the number of physics steps increases the amount of elapsed time between frames which increases the number of physics steps toward infinity

virtual void iODEDynamicSystemState::EnableStepFast bool    enable [pure virtual]
 

Enables the experimental StepFast code in ode Setting this in ODEDynamicState sets it here Only modify it if you want a specific system to behave differently.

virtual void iODEDynamicSystemState::SetCFM float    cfm [pure virtual]
 

Sets ODE's Constraint Force Mixing (see ode docs for details) Setting this in iODEDynamicState will set it for each System Use this only if you want a specific system to behave differently.

virtual void iODEDynamicSystemState::SetERP float    erp [pure virtual]
 

Sets ODE's Error Resolution Parameter (see ode docs for details) Setting this in iODEDynamicState will set it for each System Use this only if you want a specific system to behave differently.
