About this mod

A C++ Papyrus library that helps to optimize scripts. When a player has this plugin installed, mod developers can take advantage of getters, filters, sorters, and more, to make their mods more efficient, performant, and stable.

Permissions and credits
I now accept donations on my website!

For Players:

A mod developer will direct you to this plugin if their mod can take advantage of it. All you need to do is meet the two requirements, download the plugin, install, and you're ready to go!

For Developers:

When a player has this plugin installed, you can utilize SkyPal's various global scripts to handle large amounts of objects in a single function call. Instead of iterating too many objects in Papyrus and bogging down the game or even worse, dumping stacks, you can use SkyPal to natively execute batch operations for you. Currently, the most developed SkyPal script lets you interact with and handle ObjectReferences in a variety of ways. Checkout the FAQ and the examples sections for more information. You may also wish to check out the GitHub page for the source code.


  • Skyrim SE
  • SKSE 2.0.17+ (2.0.19 recommended)

Whenever Bethesda releases a new version of Skyrim, this mod will require an update, just as SKSE does. In that event, you will need to install the updated version when it comes out. For more information, see the FAQ section.


Will you use the Address Library so I don't have to update when Bethesda releases a new version of Skyrim?
The Address Library does not work that way. It cannot guarantee that an SKSE Plugin that uses it will work when a new Skyrim version comes out. It cannot guarantee that its ids will remain valid in the next version. You can read more about that on the description page of Address Library. Also, this mod is currently dependent upon SKSE as a static library. The developers of SKSE must update the addresses in their program whenever a new version of Skyrim comes out, and so too must SkyPal.

Will SkyPal be backwards compatible when it has received an update?
When an update to SkyPal occurs, there will be a strong attempt to preserve backwards compatibility. In most cases, there is no reason a function or script needs to be removed when we can just add a new one. No function will have its default parameters changed. If any function or script needs to be deprecated, it will be notated in a comment, as well as where to find the alternatives. This approach allows older mods to work with newer versions of SkyPal, so that they remain working even when their developers no longer provide updates.

Can you add this or that function?
If there is something you need that SkyPal doesn't have, talk to me and together we can develop an update that will directly assist you and your mod's needs. I may from time to time add functions and global scripts of my own accord that are useful, or exemplify what can be done better, faster, and more stably with SkyPal. However, it's better if you tell me what you actually need, so we can work on real use-cases. Feel free to message me here on Nexus!

Developer Examples:

You can check if the player has correctly installed SkyPal:
if SkyPal.Has_DLL()
    ; let's optimize
elseIf This_Mod_Has_A_Fallback()
    ; notify players that we're falling back to the slower method
    ; notify players that they did not correctly install SkyPal, and bail

Also what version they are running:
if SkyPal.Has_Version(1, 1, 0, ">=")
    ; player is running 1.1.0+, let's use newer functionality
elseIf SkyPal.Has_Version(1, 0, 0, "==")
    ; player has our fallback version
    ; can't use this version of SkyPal, bail.

Let's combine a filter and sort to greatly improve our efficiency:
ObjectReference property player auto

ObjectReference[] function Get_Refs_Near_Player(float distance = 5000.0)
    ; Get all refs currently in the cell grid around the player
    ObjectReference[] grid_refs = SkyPal_References.Grid()

    ; Pass any refs that are less than 'distance' units away from the player
    grid_refs = SkyPal_References.Filter_Distance(grid_refs, distance, player, "<")

    ; Sort them from closest to farthest away from the player
    grid_refs = SkyPal_References.Sort_Distance(grid_refs, player, "<")

    return grid_refs

Find a weapon in the player's grid that has one of the keywords, but not both:
int property weapon_form_type = 41 autoReadOnly; 'kWeapon' in SKSE's FormType script
Keyword property keyword_a auto
Keyword property keyword_b auto

ObjectReference function Get_Our_Weapon()
    ; Get all refs currently in the cell grid around the player
    ObjectReference[] grid_refs = SkyPal_References.Grid()

    ; Pass any refs that have a base form type of 'weapon_form_type'
    int[] base_form_types = new int[1]
    base_form_types[0] = weapon_form_type
    grid_refs = SkyPal_References.Filter_Base_Form_Types(grid_refs, base_form_types)

    ; Pass only refs that have one or the other keyword, but not both
    Keyword[] keywords = new Keyword[2]
    keywords[0] = keyword_a
    keywords[1] = keyword_b
    grid_refs = SkyPal_References.Filter_Keywords(grid_refs, keywords, "^")

    ; make sure we check for none
    if grid_refs.length > 0
        return grid_refs[0]
        return none
