LadyBaskerville's Miscellaneous Javascript Snippets

[LadyBaskerville]

Over the last months, I've accumulated a few code snippets I did for requests. While none of them deserves its own plugin thread, I wanted to share them somewhere in case someone else might find use in them.

They are posted below as both .js files to download and place directly in your plugins folder and as spoilered code. The contents of the .js files and the spoilers should be exactly the same, so you only need to download one or the other.

Terms of use for all following snippets:
- Free for use in both non-commercial and commercial games.
- No credit required.
- Edits and reposts allowed.

Require Living Actor
This was requested as a separate snippet from my Summon Actor plugin.
Place the notetag <Require Ling Actor: n> in a skill or item notebox to only enable the skill / item if actor #n is alive.

Shift Enemies (Version 1.1.0)
From this request thread. Allows you to shift enemy battlers outside the boundaries of the Troop window with notetags.
Use <ShiftX: n> and <ShiftY: n> in the enemy notebox to shift the battler n pixels to the right and down, respectively. Use negative values for the opposite directions.
Version 1.1.0: Added Plugin Parameters for default Shift values.

 * the <UseDefaultX/YPos> notetags for each enemy that should be placed
 * at the default position.
 *
 * You can use the following variables as part of [expression]:
 * screenWidth - the width of the game window in pixels
 * screenHeight - the height of the game window in pixels
 * troopSize - the number of enemies in the troop
 * index - the index of the enemy within the troop
 * statusHeight - the height of the status window
 * (If you know what you are doing, you can also use:

Battle Log Weaknesses
From this thread. Shows a message in the Battle Log when an elemental weakness or resistance is hit (Element Rate above or below 100%, respectively). Note: The plugin is not extensively tested and probably won't play nice with larger battle engine type plugins because it's overriding the Window_BattleLog.displayActionResults function. I may add compatibility with Yanfly's Battle Engine Core or other (free, unobfuscated) battle engine plugins at request, provided they don't make extensive changes to how the battle log is handled.

Custom Item Choices Note: This version of the plugin is outdated; the plugin now has its own thread here.
Only show specific kinds of items in the Select Item window, for when the Item Type distinction in the database isn't enough. Use the notetag <type:[customType]> in the item's notebox. Before using the Select Item command in an event, use the plugin command SetSelectItemType [customType] to only show items with the corresponding notetag in the Select Item window. Use the plugin command SetSelectItemType 0 to return to the default behavior (showing all regular items/key items/hidden items A/B in the selection window).

Spoiler: Usage Example

Here's an bare-bones example for how this plugin can be used to select seeds for planting as part of a simple farming game:

I hope someone finds use in some of these small snippets

 

[LadyBaskerville]

Update: Added a Shift Actors snippet. Might be useful for battler sheets that are larger than the standard.

 

[LadyBaskerville]

Update: Shift Enemies and Shift Actors are both updated to version 1.1.0. They now both have plugin parameters for default Shift values.

 

[LadyBaskerville]

Update: Fixed a bug with the Reflect onto Opponents snippet - when magic was reflected from multiple allies to one opponent and the opponent died before the last magic, it would cause the game to crash.

 

[Leaufai]

Thanks for making the Shift Enemies plugin. Could I suggest some added functionality?

Being able to make the positioning dynamic would be useful both for side and front view battles and would be a godsend for my game. For sideview you could use a formula to place animated SV enemies in a row, just like your team. And for front view you could use it to easily center/align enemies, which is especially useful for wide screen resolutions.

Yanfly has such as system to place your own battles dynamically, which could be used as an inspiration. Here's the code that is standard in Yanfly's Battle Engine Core for determing the X and Y of SV battlers:

X:

screenWidth - 16 - (maxSize + 2) * 32 + index * 32

Y:

screenHeight - statusHeight - maxSize * 48 + (index+1) * 48 - 32

@Leaufai I would rather make that its own little plugin, since it's not really "shifting" the enemy from the position in the troop window, but instead placing them at a position directly. Actually, I liked the idea so much that I just programmed it: EnemyPlacement.js

 

[Joy Diamond]

LadyBaskerville,

@LeaufaiActually, I liked the idea so much that I just programmed it: EnemyPlacement.js

Very nice sample code for a small plugin, LadyBaskerville.

Also I *really* appreciate that it has a license in it:

* Free for use in both non-commercial and commercial games.
* No credit required.
* Edits and reposts allowed.

I'll use it as a starting point for the plugin's I'll be writing.​

Thanks,

Joy Diamond.

P.S.: I think the google drive you used to share the drive is really a good way for sharing.

P.P.S.: So since I'm sharing songs I'm listening today, right now I am listening to Lindsey Stirling & KHS (youtube link) ... another very inspiring song when programing

 

[Leaufai]

@LadyBaskerville Awesome! I'll try it out as soon as possible!
@Joy Diamond Agreed, cool song.

EDIT: I tried it out. Very versatile. Here's a screenshot of how I'm using it:

Works like a charm. Only suggestion is maybe adding the default settings for the X and Y to the parameter description. Helps people get back to them after they try other things out.

 

[LadyBaskerville]

@Leaufai That looks cool! And good point about writing the default settings down for reference. I've just added them to the parameter descriptions and also at the bottom of the help file (because I just noticed that you can't actually copy and paste them from the parameter description itself ...)

 

[Leaufai]

Hey @LadyBaskerville, I think I've encountered a bug in the Enemy Placement. The first time I do a battle it works fine, but the second time the enemies are nowhere to be seen (although I can fight them).

What can I get you to help you fix this problem?

 

[LadyBaskerville]

@Leaufai I already found my mistake - I messed up how the statusHeight variable was calculated, so it would accidently be multiplied each time a battle started Version 1.0.1 is now in the opening post.

 

[Leaufai]

Hah, that's a hilarious bug. Glad for fixing it so quickly. Battle system is starting to take shape, in part due to this excellent plugin

 

[LadyBaskerville]

Update: Fixed a bug with the Weapon Over Actor snippet that would occur when an actor had no weapon equipped.

Shift Enemies (Version 1.1.0)
From this request thread. Allows you to shift enemy battlers outside the boundaries of the Troop window with notetags.
Use <ShiftX: n> and <ShiftY: n> in the enemy notebox to shift the battler n pixels to the right and down, respectively. Use negative values for the opposite directions.
Version 1.1.0: Added Plugin Parameters for default Shift values.
Download as plugin
When you create the .js file yourself, make sure it is named "ShiftEnemies.js".

Before I experiment too much and break things like a noob... is it possible to apply these shift codes (Shift Enemies & Shift Actors) to states instead of enemy/actor notetags?

 

[Marillmau5]

Just what I needed thanks for the shift enemies!

 

[EmmieFinch]

so i was using the reflect onto opponents plugin, to see if it could have an opponents attack reflect onto me, but it still went to the (enemy) attacker, instead of the party.

 

[Aera Colthearts]

Regarding about EnemyPlacements
Is there any way to change default X / Y position through script call or plugin command? I wish to change them mid game.

 

[LadyBaskerville]

Update: Added a small plugin for Custom Item Choices to the first post!

---

@Pelnar I realize my response comes about a year too late, but to answer you anyway: It's technically possibly, but not with the current version of the plugins - unfortunately, I currently don't have the time to include that option. Sorry! But feel free to ask in Plugin Requests with a link to here if you still need it.

@EmmieFinch Very sorry for the extremely late reply. I'll look into it when I have the time - just going by the code, it looks like it should work the way you describe, but I may have missed something there.

@Aera Colthearts Not currently, but it should be possible with a few small modifications. I'll see if I can add that within the next week or so. (For now, a slightly hacky way to do it would be to reference a game variable in the parameters/notetags and store the current X/Y position formula in that variable as a string - but script call/plugin command would be neater.)

 

[LadyBaskerville]

Update: Added a small plugin to display elemental weaknesses and resistances in the Battle Log.

CustomItemChoices now has its own thread with a new version of the plugin here.
