Shader Effects II

The ShaderFX engine allows trigger screen shaders and post-processing filters through datapack events based on combat context.

💡 What's New in v2.2: I have completely deprecated the old, complex & redundant "Shader Packets Parameters" system. In the modern version, it's more understandable and redundant entries have been eliminated. The system now operates with sealed records, allowing for more efficient shader addition, since previously compatibility with a centralized record was forced. Additionally, the Shader loader now operates as a Coroutine and not as a tickable event, this eliminates various bugs, such as retaining visual effects while active and exiting the world (if it was of the holdable type).

📄 File Structure & Schema

Field	Description	Valid Options
category	Target weapon category (Required).	e.g., epicfight:sword
trigger_item	Targeted item id. Defaults to all if missing.	"all" or "modid:item_id"
activation_type	The root gameplay trigger context.	"Skill", "Style", "Animation"
effect	The effect in question with its respective data.	All shaders

🔄 Matrix (Valid Pairings)

• Skill ➡️ When a skill is active, primarily of the time type for Weapon Innate (Like Longsword).
• Style ➡️ As long as the configured style is the same as the one that holds the item.
• Animation ➡️ At the moment an animation is executed.

1. BiColor Overlay

Supported in: Skill (Hold), Style (Hold) Parameters:

• time_in (Fade-in)
• time_out (Fade-out)
• intensity

• dark_color (R, G, B Integer)
• light_color (R, G, B Integer)

BiColor Overlay - Example

In this example, upon entering demonic ascension, the game experiences a shift in its dark colors to black and its light colors to white, causing a grayscale effect controlled only by the intensity of the effect.

{

      "trigger_item": "wom:antitheus",
      "activation_type": "style",

Animation-Based Temporary Effects

Besides dedicated animation effects such as Noise Overlay and Impact Frame, animations can also trigger temporary versions of standard screen shaders.

These effects execute once when the animation reaches the configured elapsed time and remain active for the specified hold duration.

Supported effects:

• bi_color_overlay
• focus_blur
• crt_filter
• glow
• phase_noise
• sharpen

Required parameters:

Parameter	Description
time_in	Fade-in duration
time_hold	Time the effect remains active
time_out	Fade-out duration

OneShot - Glow - Example

By holding Moonless and using its innate ability, we will cause a glow effect

🎞️ Combinations

Furthermore, the effects are not "unique"; the same category and/or items can trigger several shaders at the same time. In this example, executing the "battojutsu" animation will execute 2 shaders, while with its dash version ("battojutsu_dash"), we will execute another 2.

⚠️ Behavior

When the specified animation reaches the configured elapsed time:

1. The overlay fades in during timein.
2. Remains active for hold.
3. Fades out during timeout.
4. Automatically cleans itself once finished.

🔗 Configuration Reminder

Any incorrect values, or potential errors, will be displayed in the Log; a crash will no longer occur as in past versions, your shader simply won't do anything!
