Roblox has recently released an API for trackpad gestures. As seen previously in this thread, trackpad users can only scroll via the drag bar with this module’s current state. I am working on adding proper trackpad support, and will then update this thread and the model.
I have a functioning prototype.
However, it falls into the problem of CAS vs. UIS that has been discussed throughout this thread. Because the API is currently UIS-only, there is no way for me to sink the input.
Because of this, this feature may have to wait until Roblox adds trackpad support into the CAS API as well. I have asked them about this, so we shall see.
