Remote activation of the Movement Modulator device does not work properly with physics

Summary

I’m trying out the movement modulator device while the physics are active. Everything about movement modulator device is fine, expect remote activation. When I activate it remotely with the signal remote, it affects the character’s movement speed but does not apply any impulse force.

What Type of Bug are you experiencing?

Devices

Steps to Reproduce

1- Enable physics via project settings
2- Add movement modulator device to map (Apply Impulse = true, Forward Impulse = 2000, Apply Remote Impulse Relative To Player Direction = true)
3- Add signal remote manager device to map (Signal remote tier common)
4- Register movement modulator activate function to Signal remote manager’s On primary activation event
5- Equip common signal remote and input primary action

Expected Result

Character should dash forward

Observed Result

The movement modulator does not apply impulses to the character

Platform(s)

Hello! Thanks for the feedback! The Movement Modulator isn’t fully compatible when physics is enabled. The reason for this is that when you enable physics, the character spawns as a physically based character. It moves via forces being applied to the body. While the field is called “Impulse”, the device is applying “force” to the non-physics character. We need to upgrade this portion of the device to work with the physics character. We are continually working on the devices. We prioritized ones that apply force and need to work through all the others over time.

What kind of gameplay are you trying to implement? It helps us understand priority order of upgrading devices.

I saw my post was flagged as a duplicate of this one.

I think remote activation of movement modulator is mainly used to create a “Dash” ability.
I was trying to create a map with low gravity but without Dash there’s no easy way to let players control their characters.

Understood. This dash was to create which type of game? Are you interested in a combat style game? Parkour? Open world? Just trying to understand what sort of control you’re looking for over the player.

In my case Sports style game so Dash would be used mostly for mobility.

Hello, sorry for the late reply. I was also looking to use it to create a dash ability. The game I’m trying to create is a soccer game. The current character’s movements aren’t enough to make the game fun. I thought a dash ability would make the game more fun and challenging. Currently, the character is physics-based, so it lacks a lot of items and abilities. Because of this, I haven’t been able to incorporate many of the fun ideas I’ve come up with into the game, and I hope to see these fixed in future updates.

I was using it to create a sort of dash ability and double jump in a parkour based game! Hope we can get the Movement modulator to apply remote impulses supported in the near future! Also loved your talk on juicing was amazing to see!
