I’ve sort of recoded a free model script to fit my style, this model is a rain script.
The issue I’m getting is on line 149: attempt to perform arithmetic (mul) on Vector3 and table, and have no idea why.
This is the server script.
local rain = require(script.Rain)
rain:setColor(Color3.fromRGB(script.Color.Value.x, script.Color.Value.y, script.Color.Value.z))
rain:setTransparency(script.Transparency.Value)
rain:setSpeedRatio(script.SpeedRatio.Value)
rain:setIntensityRatio(script.IntensityRatio.Value)
rain:setLightInfluence(script.LightInfluence.Value)
rain:setLightEmission(script.LightEmission.Value)
rain:setVolume(script.Volume.Value)
rain:setDirection(script.Direction.Value)
rain:setStraightTexture(script.StraightTexture.Value)
rain:setTopDownTexture(script.TopDownTexture.Value)
rain:setSplashTexture(script.SplashTexture.Value)
rain:setSoundId(script.SoundId.Value)
local threshold = script.TransparencyThreshold.Value
if script.TransparencyConstraint.Value and script.CanCollideConstraint.Value then
rain:setCollisionMode(rain.CollisionMode.Function, function(p)
return p.Transparency <= threshold and p.CanCollide
end)
elseif script.TransparencyConstraint.Value then
rain:setCollisionMode(rain.CollisionMode.Function, function(p)
return p.Transparency <= threshold
end)
elseif script.CanCollideConstraint.Value then
rain:setCollisionMode(rain.CollisionMode.Function, function(p)
return p.CanCollide
end)
end
rain:Enable()
This is the module script that handles the main events.
