Blood Engine • V1.1.3

↳ General Changes

• A new size setting: Added a new setting: YSize, which controls the range of the y size of the pool, giving you the ability to make it flat or thick. (Reference to suggestion: https://devforum.roblox.com/t/blood-engine-a-droplet-emitter-system/2545682/239)

Blood Engine • V1.1.2

↳ General Changes

• A new Destroy method: Added a Destroy method, that I admit should have been there in the beginning. This is for developers who especially use StarterCharacterScripts. (Reference to issue: https://devforum.roblox.com/t/blood-engine-a-droplet-emitter-system/2545682/233)

Blood Engine • V1.1.1

↳ General Changes

• Fixes: Fixed an issue where if no Data/Settings table was provided, the module would error. This is in reference to this issue: https://devforum.roblox.com/t/blood-engine-a-droplet-emitter-system/2545682/224

Blood Engine • V1.1.0

↳ General Changes

• Improvements to Emission: You can now emit mixed droplets (decal & default) without making a new emitter instance!
• Droplet Color: There's a new DropletColor setting to change the color of your droplets/pools.

↳ Other Notes

While this was a minor update, what you can do with it is anything but.
Here's a showcase to show what you can do with this new release:

d1cc8933b54b3b42df563da78f10c747.mp4

You can now do a mix of Droplets and Decals. And without creating multiple emitter instances that might eat out your performance.
Here's the code behind it:

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local BloodEngine = require(ReplicatedStorage.BloodEngine)
local Engine = BloodEngine.new({
	Limit = 500,
})

local EMIT_AMOUNT = 50
local EMIT_DELAY = 5

local function Emit()
	-- A random chance of the droplet being a decal
	local IsDecal = math.random(0, 1) == 1
	
	-- Emits a droplet in a random direction relative to a part, and there's a chance that it could be a decal.
	Engine:Emit(script.Parent, nil, {
		Type = IsDecal and "Decal" or "Default",
		DefaultSize = IsDecal and { 1, 1.4 } or { 0.4, 0.7 }
	})
end

-- A custom iteration of the EmitAmount method
while true do
	for Index = 1, EMIT_AMOUNT, 1 do
		local DropletDelay = math.random(0.05, 0.1)

		Emit()
		task.wait(DropletDelay)
	end
	task.wait(EMIT_DELAY)
end

Blood Engine • V1.0.3

↳ General Changes

• Small Fixes: There weren't really any changes to the code, this update is more focused on assets. A certain decal was removed due it bugging out, and I made some changes to the properties of the droplets for a certain upcoming bugfix.

Blood Engine • V1.0.2

↳ General Changes

• Different Settings Upon Emission: You can now apply different settings to the droplets using EmitAmount or Emit instead of manually changing it.

Blood Engine • V1.0.1

↳ General Changes

• Bugfixes: The Pool Expansion feature had this bug where it would unexpectedly expand beyond its limit. This occurred due to a droplet interacting with a pool mid-expansion, which expands it twice as much.

Blood Engine • V1.0.0

↳ General Changes

• Comprehensive Rewrite: The module has undergone a complete rewrite, enhancing its readability and ease of modification. This overhaul also improves the organization of the code, making it easier to locate specific elements.

• Pool Expansion: Reintroducing the Pool Expansion feature, now enhanced with effects and new options such as:

• Expansion: A toggle switch for this feature.
• Distance: Defines the distance (in studs) within which a droplet should check for nearby pools.
• ExpanseDivider: Controls the rate of pool size increase. Higher values result in a slower increase.
• MaximumSize: Sets the maximum size a pool can reach.

• Ignore Players: The IgnorePlayers option has been permanently removed. However, a guide on how to make droplets ignore players will be released in the future.

• Splashing: Expanded the options for the splashing feature, providing more customization possibilities:

• SplashName: The name of the attachment that releases particles on surface contact.
• SplashByVelocity: If true, sets the number of particles based on the velocity of the droplet.
• VelocityDivider: Controls the extent to which velocity can influence the splash amount. Higher values will lessen the effect.

• Additional Options: Added and revamped several options to provide you with more control over the appearance of the droplets, pools and effects, as well as the functionality of the module:

• FolderName: Specifies the name of the folder containing the droplets.
• Type: Defines the droplet type. It can be either "Default" (Sphere) or "Decal".
• DefaultTransparency: Specifies the default transparency range of a pool.
• Trail: Controls the visibility of the trail during droplet emission.
• StartingSize: Sets the initial size of the droplets upon landing.
• ScaleDown: Determines whether the pool should scale down when decaying.
• Tweens: Contains all the tweens used by the module: Decay, Land and Expand

Blood Engine • V0.0.6

↳ General Changes

• Accurate Raycasting: Implemented accurate raycasting using FastCast for improved precision.

• Splash Effects: Introduced splash/impact effects to enhance visuals, includes the SplashAmount option, which manages how many particles to emit.

• Ignore Players: Added the ability for the droplets to ignore players with the IgnorePlayers option, prevents any interaction between them.

• Removal of Features: Temporarily removed the PoolExpansion feature. It is planned to be reintroduced in a future update following a rewrite to clean things up.

↳ Other Notes

The system's feature set has grown unexpectedly, leading to cluttered and sorta hard-to-read code. A module rewrite is planned, including a complete rewrite of this post.

Blood Engine - V0.0.5

General:

• Included a showcase place on the GitHub.
• Added a more efficient way to change the settings: UpdateSettings.
• Resolved an issue that prevented the proper removal of excess droplets.
