Detailed Description

Physics model.

Thrust/drag/lift: The Physics class doesn't need to transform thrust/drag/lift (excluding weight). These force vectors are relative to a Craft and therefore exist in local space. Ultimately these are passed to Dyna::Translate(Vector3) which transforms them.

Weight: The direction of the weight vector is fixed/absolute of course. Weight acceleration can be applied using Object::GetPosition()/SetPosition() to directly add weight vector in terms of a world vertex.

Member Function Documentation

void mod_base::Physics::EnableAll

(

bool

enable

)

Enable all instances or this instance.

void mod_base::Physics::Enable

(

bool

enable

)

void mod_base::Physics::SetEyeCraft

(

void

)

Configure Physics model for EyeCraft. Vector directions are different for EyeCraft than other Craft (a consequence of Eye having a different matrix polarity).

void mod_base::Physics::Reset

(

void

)

Called when Craft is reset.

void mod_base::Physics::MoveObject

(

void

)

Move Object in World Space according to net force vectors. Manipulates Object using Object interface.

Vector3 mod_base::Physics::ComputeSpeed

(

void

)

Compute speed. Really return mSpeed computed prior.

fp mod_base::Physics::ComputeSpeedMach

(

void

)

Returns:

Speed in Mach number (float).

fp mod_base::Physics::GetMaxMach

(

void

)

bool mod_base::Physics::IfStall

(

void

)

Returns:

True if stalling.

fp mod_base::Physics::ComputeStall

(

void

)

Compute fraction indicating the amount of stalling (1.0 is total stall).

Precondition:

IfStall() was called prior and returned true -- else undefined!

void mod_base::Physics::SetSpeedMach

(

const fp

mach

)

Setters.

void mod_base::Physics::SetThrust

(

const Vector3 &

thrust

)

void mod_base::Physics::SetMaxThrust

(

const Vector3 &

maxThrust

)

void mod_base::Physics::SetMaxSpeed

(

const Vector3 &

maxSpeed

)

void mod_base::Physics::SetMaxMach

(

const fp

maxMach

)

void mod_base::Physics::SetStallMach

(

const fp

stallMach

)

fp mod_base::Physics::Mach2Speed

(

const fp

mach

)

[private]

Convert between artificial speed and Mach.

fp mod_base::Physics::Speed2Mach

(

const fp

speed

)
