solved Chance of talking when in radius of an entity

[RadiantRoma]

My character has mottephobia, AKA fear of butterflies and moths! I have it so they lose sanity when in a radius of a butterfly, but I wanted there to be a chance of them announcing when they get near a butterfly. I got everything right, except I probably don't have the math.random() done right, because when the chance < 0.50, they never say it. But when I change it to chance < 0.75, they say it every time. Here's the code.

	local chance = math.random()
--near butterfly
	inst:DoPeriodicTask(
            0.1,
            function(inst)
                local x, y, z = inst.Transform:GetWorldPosition()
                local ents = TheSim:FindEntities(x, y, z, 4.0, {"butterfly"})
                if #ents > 0
                then
                    if inst.wisniowski_mottephobia == nil
                    then
                        

						if chance < 0.50 then
							inst.components.talker:Say(GetString(inst.prefab, "ANNOUNCE_BUTTERFLY"))
							inst.components.sanity.dapperness = (TUNING.DAPPERNESS_LARGE * -1)
							inst.wisniowski_mottephobia = true
						else
							inst.components.sanity.dapperness = (TUNING.DAPPERNESS_LARGE * -1)
							inst.wisniowski_mottephobia = true
						end

						
                    end
                else
                    if inst.wisniowski_mottephobia ~= nil
                    then
                    	inst.components.sanity.dapperness = (TUNING.DAPPERNESS_SMALL * -1)
						inst.wisniowski_mottephobia = nil
                    end
                end
            end
    	)
	

Any help is appreciated!

replace "chance < 0.50" with "math.random() < 0.50" in your code (and remove local chance...above)

The way it is at the moment chance is set one time, so it will be always eg. 0.3, without changing. The result is always your text or never.

Works! Thanks a ton!

Wouldn't calling this code every .1 seconds cause lag or something? Just wonderin' ...

From what I can tell, it doesn't. All it's doing anyway is adding a couple lines of code. But if you know another way that undeniably is impossible to cause lag, I could try it out!
