Can y'all simplify/shorten this function?

for _, button in pairs(SolidModelingButtonsArray) do

I’d say this is the perfect question to ask chatgpt. With that said you could probably just break this down into smaller functions so instead of having a for loop and then doing

for _.button in pairs()

button.MouseButton1Click:Connect(function()

end)

end

You could try doing

for _,button in pairs()
button.MouseButton1Click:Connect(onButtonPress)
end

And then really just determine what maybe should and shouldn’t be part of that function. You could also shorten things to a single line like if debounce then return end.

Simplification code code can be done by finding repeated patterns within the code. In this case, within 3 of the 4 if statements, the following is the exact same:

We can condense that by changing the way the if statements are handled, like so:

if button == UnionButton or button == IntersectButton or button == SubtractButton then
	local otherParts = SolidModelingFunctionsModule.GetOtherParts()
	if next(otherParts) == nil then
		print("more parts need to be selected")
		return
	end
	local success, newParts = pcall(function()
		if button == UnionButton then
			return GeometryService:UnionAsync(CommonlyUsedVariablesModule.mainPart, otherParts, {SplitApart = false})
		elseif button == IntersectButton then
			return GeometryService:IntersectAsync(CommonlyUsedVariablesModule.mainPart, otherParts, {SplitApart = true})
		elseif button == SubtractButton then
			return GeometryService:SubtractAsync(CommonlyUsedVariablesModule.mainPart, otherParts, {SplitApart = true})
		end
	end)
	if success and newParts then
		SolidModelingFunctionsModule.NewPartsFinishingTouches(newParts, otherParts)
	end
elseif button == SeparateButton then
    ...

This can be further condensed through the use of tables, but wouldn’t recommend unless you’re comfortable with reading the self.method(self, ...) method syntax.

local operations = {
	[UnionButton] = GeometryService.UnionAsync,
	[IntersectButton] = GeometryService.IntersectAsync,
	[SubtractButton] = GeometryService.SubtractAsync,
}
if operations[button] then
	local otherParts = SolidModelingFunctionsModule.GetOtherParts()
	if next(otherParts) == nil then
		print("more parts need to be selected")
		return
	end
	local success, newParts = pcall(function()
		return operations[button](GeometryService, CommonlyUsedVariablesModule.mainPart, otherParts, {SplitApart = false})
	end)
	if success and newParts then
		SolidModelingFunctionsModule.NewPartsFinishingTouches(newParts, otherParts)
	end
elseif button == SeparateButton then
    ...

Which you’ll then notice, this syntax can just be thrown directly into the pcall. (since we’re returning the value of the operation anyways)

local success, newParts = pcall(function()
	return operations[button](GeometryService, CommonlyUsedVariablesModule.mainPart, otherParts, {SplitApart = false})
end)

-- can become:
local success, newParts = pcall(
	operations[button], 
	GeometryService, 
	CommonlyUsedVariablesModule.mainPart, 
	otherParts, 
	{SplitApart = false}
)
-- wouldn't recommend one line in this case

Some other notes:

if debounce == true then 
-- this can be replaced with
if debounce then

for _, button in pairs(SolidModelingButtonsArray) do
-- you can use the general Luau iterator
for _, button in SolidModelingButtonsArray do
-- has the benefit of doing the jobs of both ipairs and pairs so nothing ever breaks

Final Simplification

for _, button in SolidModelingButtonsArray do 
	button.MouseButton1Click:Connect(function()
		if debounce then
			return
		end
		debounce = true
		
		local operations = {
			[UnionButton] = GeometryService.UnionAsync,
			[IntersectButton] = GeometryService.IntersectAsync,
			[SubtractButton] = GeometryService.SubtractAsync,
		}
		if operations[button] then
			local otherParts = SolidModelingFunctionsModule.GetOtherParts()

			if next(otherParts) == nil then
				print("more parts need to be selected")
				return
			end

			local success, newParts = pcall(
				operations[button], 
				GeometryService, 
				CommonlyUsedVariablesModule.mainPart, 
				otherParts, 
				{SplitApart = false}
			)

			if success and newParts then
				SolidModelingFunctionsModule.NewPartsFinishingTouches(newParts, otherParts)
			end
		elseif button == SeparateButton then
			SolidModelingFunctionsModule.CleanUp()

			local otherParts = SolidModelingFunctionsModule.GetOtherParts()
			SolidModelingFunctionsModule.RejuvenateChildren(CommonlyUsedVariablesModule.mainPart)

			for _, otherPart in otherParts do
				SolidModelingFunctionsModule.RejuvenateChildren(otherPart)
			end
			
			ButtonSelectionFunctionsModule.SelectDoublePreviousToolBarButton()
		end

		task.wait(0.1)
		debounce = false
	end)
end

Guest_2000123145:

	debounce = true

		if button == UnionButton then
			
			local otherParts = SolidModelingFunctionsModule.GetOtherParts()

			if next(otherParts) == nil then
				print("more parts need to be selected")
				return
			end

you exited the function without setting debounce back to false.
consider

task.delay(0.1, function() debounce = false end)

instead of setting false at the end of the function
