  2. Impulse Force COMP

    Impulse Force COMP

    Summary

    An Impulse Force COMP will create a force in the simulation that can be applied for 1 frame using the Pulse Force parameter. In the real world, impulse forces are forces applied over a very short duration, however in Bullet this is somewhat simplified, and they are instead applied instantly (for a single frame). Examples of impulse forces are kicking a ball or shooting a cannon. The velocities of the affected bodies are changed in an instant by the impulse force, and after that instant the force no longer has an effect unless applied again.

    The resulting velocity of the bodies after the impulse force is applied is the same as the Force COMP with the same values if the Force COMP is applied for exactly 1 second. For example, if 10N of Impulse Force is applied to a body with mass 5kg then the resulting velocity will be 10N / 5kg * 1sec = 2m/s.

    Parameters - Force Page

    Pulse Force pulse - Pulse for the impulse force. When pulsed, on the next frame it will apply the impulse force.

    Force force - ⊞ - The linear force in Newtons to be applied when the node is pulsed.
    • X forcex -
    • Y forcey -
    • Z forcez -
    Relative Position relpos - ⊞ - The position at which to apply the linear force, relative to the center of the body (Note: the physical center of the object, not the center of mass). Having a nonzero relative position will also cause the body to rotate due to added torque.
    • X relposx -
    • Y relposy -
    • Z relposz -
    Torque torque - ⊞ - The rotational force in Newtons that will be applied.
    • X torquex -
    • Y torquey -
    • Z torquez -

    Parameters - Extensions Page

    The Extensions parameter page sets the component's python extensions. Please see extensions for more information.

    Extension ext - Sequence of info for creating extensions on this component

    Object ext0object - A number of class instances that can be attached to the component.

    Name ext0name - Optional name to search by, instead of the instance class name.

    Promote ext0promote - Controls whether or not the extensions are visible directly at the component level, or must be accessed through the .ext member. Example: n.Somefunction vs n.ext.Somefunction

    Re-Init Extensions reinitextensions - Recompile all extension objects. Normally extension objects are compiled only when they are referenced and their definitions have changed.


    Parameters - Common Page

    The Common parameter page sets the component's node viewer and clone relationships.

    Parent Shortcut parentshortcut - Specifies a name you can use anywhere inside the component as the path to that component. See Parent Shortcut.

    Global Shortcut opshortcut - Specifies a name you can use anywhere at all as the path to that component. See Global OP Shortcut.

    Shortcut iop0shortcut - Specifies a name you can use anywhere inside the component as a path to "Internal OP" below. See Internal Operators.

    OP iop0op - The path to the Internal OP inside this component. See Internal Operators.

    Node View nodeview - ⊞ - Determines what is displayed in the node viewer, also known as the Node Viewer. Some options will not be available depending on the Component type (Object Component, Panel Component, Misc.)
    • Default Viewer default - Displays the default viewer for the component type, a 3D Viewer for Object COMPS and a Control Panel Viewer for Panel COMPs.
    • Operator Viewer opviewer - Displays the node viewer from any operator specified in the Operator Viewer parameter below.
    Operator Viewer opviewer - Select which operator's node viewer to use when the Node View parameter above is set to Operator Viewer.

    Keep in Memory keepmemory - Used only for Panel Components this keeps the panel in memory to it doesn't reload every time it is displayed.

    Enable Cloning enablecloning - Control if the OP should be actively cloneing. Turning this off causes this node to stop cloning it's 'Clone Master'.

    Enable Cloning Pulse enablecloningpulse - Instantaneously clone the contents.

    Clone Master clone - Path to a component used as the Master Clone.

    Load on Demand loadondemand - Loads the component into memory only when required. Good to use for components that are not always used in the project.

    External .tox externaltox - Path to a .tox file on disk which will source the component's contents upon start of a .toe. This allows for components to contain networks that can be updated independently. If the .tox file can not be found, whatever the .toe file was saved with will be loaded.

    Reload .tox on Start reloadtoxonstart - When on (default), the external .tox file will be loaded when the .toe starts and the contents of the COMP will match that of the external .tox. This can be turned off to avoid loading from the referenced external .tox on startup if desired (the contents of the COMP are instead loaded from the .toe file). Useful if you wish to have a COMP reference an external .tox but not always load from it unless you specifically push the Re-Init Network parameter button.

    Reload Custom Parameters reloadcustom - When this checkbox is enabled, the values of the component's Custom Parameters are reloaded when the .tox is reloaded. This only affects top-level parameters on the component, all parameters on nodes inside the component are always reloaded with the .tox.

    Reload Built-In Parameters reloadbuiltin - When this checkbox is enabled, the values of the component's built-in parameters are reloaded when the .tox is reloaded. This only affects top-level parameters on the component, all parameters on nodes inside the component are always reloaded with the .tox.

    Save Backup of External savebackup - When this checkbox is enabled, a backup copy of the component specified by the External .tox parameter is saved in the .toe file. This backup copy will be used if the External .tox can not be found. This may happen if the .tox was renamed, deleted, or the .toe file is running on another computer that is missing component media.

    Sub-Component to Load subcompname - When loading from an External .tox file, this option allows you to reach into the .tox and pull out a COMP and make that the top-level COMP, ignoring everything else in the file (except for the contents of that COMP). For example if a .tox file named project1.tox contains project1/geo1, putting geo1 as the Sub-Component to Load, will result in geo1 being loaded in place of the current COMP. If this parameter is blank, it just loads the .tox file normally using the top level COMP in the file.

    Re-Init Network reinitnet - This button will re-load from the external .tox file (if present), followed by re-initializing itself from its master, if it's a clone.
