Keep Bullet not going downwards

[Nimagalo_xxl (DrakeLamar)]

I wanna set the cframe so that it does not go down and it just goes a straight line instead of going down, im a bit confused on why it points down

			local currentCFrame = plr.Character.PrimaryPart.CFrame * CFrame.new(0,0,-4)
			local orientationX, orientationY, orientationZ = currentCFrame:ToOrientation()

			
			bool2.CFrame = currentCFrame * CFrame.Angles(math.rad(0),0,0)
			
			 --* CFrame.Angles(0,1,1)
			
			local tween = game.TweenService:Create(bool2,TweenInfo.new(1.5),{["CFrame"] = (bool2.CFrame*CFrame.new(0,0,-75))})
			tween:Play()

im trying to make it so the X rotation value of the cframe always stays 0, so it can go straight

The issue is that you are multiplying the existing CFrame by an angle instead of resetting the rotation entirely. You should construct a new CFrame using only the position from your currentCFrame and a fixed rotation vector, like CFrame.new(currentCFrame.Position). This way, the X axis stays at zero because you aren’t inheriting the old orientation.
