Weapons in my game have a considerable impact on movement

Help and Feedback Scripting Support
#1

So in my FPS I have some custom movement code. It works great when the user isn’t holding anything, but if they have a tool equipped then acceleration seems to be heavily weighted to one side of their body. I think it might be some kind of interaction with the body gyro that I use to prevent users from tripping. I have all weapons set to massless, but the weight of the weapons still appears to apply. If I reduce the density using custom physical properties to .01 then that also apparently reduces the effect the weapons have on the user.

Any ideas on how I can separate the weight of the tool entirely?

#2

Set the Massless property of all of the parts affecting the player to true.

#3

I’ve already done this. Not sure why but it seems to get ignored/make no difference. Only the density prop does.

#4

Can you send a model of one of the weapons? (without scripts)

#5

Turn cancollide off on all le parts

#6

I actually have a theory that it’s not about weight, it’s how changing the density forces Roblox to recalculate the physics assembly or something? I think a Weld might be getting cached wrong. Still looking into it.

#7

Make sure that ALL the parts are set to CanCollide and Massless false.
If even one part is left out it can still make the physics go weird.

#8

Here’s what I do on weapon copy

           for i, v in pairs(newTool:GetDescendants()) do
				if v:IsA("BasePart") then
					v.Massless = true
					v.CanCollide = false
					v.CustomPhysicalProperties = PhysicalProperties.new({
						Density = .01,
						.3,
						.5
					})
				end
			end
#9

Try getting rid of the thing that sets CustomPhysicalProperties

#10

That line was definitely off but it doesn’t seem to work either way, with the corrected constructor or removed.

#11

Are you sure there’s no other parts being attached to the character?

I’m gonna close this question for now, there seems to be a bigger issue with it as a whole and I’ll need to do some digging. Replication is super inconsistent and seems to be more related to weapon switching than the weapons themselves.
