Description:

NEW in 3ds Max 2014: The mP_Force operator accepts any force-type particle space warp as a force source. The force is applied to all particles in the current event that are affected by an mP_World operator.

Constructors:

    mP_Force...
    PhysXForce...

Properties:

## Parameters rollout

### Force Space Warps group of controls

    <mP_Force>.Force_Space_Warps     ArrayParameter    default: #()   --  node array; SubAnim

Get/set the list of Force Space Warp objects to be used for the physical particle simulation.

    <mP_Force>.Force_Type     Integer    default: 0   --  integer

Get/set the selection of the "Force Type" drop-down list.

Possible values are:

0 - Uniform (default)

1 - Gravity

2 - Surface

    <mP_Force>.Force_Variation_Threshold     BooleanClass    default: false   --  boolean

Get/set the state of the "Force Variation Threshold" checkbox.

    <mP_Force>.Shape_Size     Float    default: 1.0   --  worldUnits

Get/set the value of the "Shape Size" spinner.

    <mP_Force>.Force_Overlapping     Integer    default: 0   --  radiobtnIndex

Get/set the state of the "Force Field Overlapping" radio buttons.

Possible values are:

0 - Additive

1- Maximum

    <mP_Force>.Influence     Float    default: 1000.0   --  animatable; percent; Controller Scaling: (1 : 100.0)

Get/set the value of the "Influence %" spinner.

    <mP_Force>.Exponent     Integer    default: 0   --  integer

Get/set the value of the "Exponent (10**N)" spinner.

    <mP_Force>.Sync     Integer    default: 0   --  integer

Get/set the selection of the "Sync By" drop-down list.

Possible values are:

0 - Absolute Time (default)

1 - Event Duration

2 - Particle Age

    <mP_Force>.Impulse_On_Event_Entry     BooleanClass    default: false   --  boolean

Get/set the state of the "Impulse On Event Entry" checkbox.

    <mP_Force>.Time_Warp     Integer    default: 4800   --  integer

Get/set the value of the "Time Warp" spinner.

When the "Use Script Wiring" option is checked in the context menu of the mP_Force operator, or set via the .setUseScriptWiring() method in Interface: action, an additional rollout becomes available.

## Script Wiring rollout (optional)

    <mP_Force>.Use_Script_Float     Integer    default: 0   --  integer

Get/set the state of the "Influence Parameter Wiring" radio buttons.

Possible values are:

0 - Not Wired (default)

1 - From Script Float

2 - From Data Operator
