currently 3 particle types are implemented

static_particle

• a simple 8x8 circle texture
• configurable color, alpha, startSize, size, endSize, lifetime
• is emissive (glow in the dark)

static_flash

• mimics the vanilla flash particle
• configurable color, alpha, startSize, size, endSize, lifetime
• is emissive (glow in the dark)
• the vanilla flash particle texture is remade from scratch to be cleaner, as well as higher resolution (64x64, previously 32x32)

static_oriented

• a simple 8x8 circle texture
• configurable color, alpha, startSizeX, sizeX, endSizeX, startSizeY, sizeY, endSizeY, lifetime, rotation, post_rotation, cull
• is emissive (glow in the dark)

all number arguments(the particle parameters) support ranges ("x..y"=random from x to y), rotation arguments also support ~ which will use the command rotation context on the appropriate axis

also if youre wondering, post_rotation is just a second pass of rotation, technically redundant, just convenient

there are also 2 standalone commands

/setfov <targets> <float> [interpolation type] [interpolation duration]

• sets the client FOV of the targets

/rendertext <targets> <alignment> <x> <y> <text> <size> [duration] [opacity] [gui scale independent] [hide with HUD]

• displays text on the targets screens at the inputted position
• boolean argument for making the text size independent of the clients GUI scale setting
• boolean argument for forcing the text to display even if the HUD is hidden (F1)

the mod also adds two conditions for predicates

mouse condition

{
  "condition": "staticparticle:mouse_button",
  "button": "left"/"middle"/"right",
  "context": "in_game"/"in_menu"
}

• true when the target of the predicate is holding the respective buttons in the respective context
• for now is hardcoded to the mouse buttons, rather than attack pick block and interact bindings

key condition

• the mod adds 5 new keybinds that dont do anything, except for tell the server theyve been pressed by a client

{ 
  "condition": "staticparticle:special_key",
  "key": 0/1/2/3/4
}

• true when the target of the predicate is holding the respective key
