Can't get haptic effect to work in UE4 with touch controllers

Hi sorry for the later reply. OK here is how it works for me. btw I am running UE4.14

First thing to do is create a variable with is an enum assigned to "Hands Enum"

In the player controller create a custom event ie RumbleLeft, then from this you want to drag off and use the Set Haptics by Value" node. In this node select frequency and amplitude and also which hand, then add a delay and then stop haptic effect. The delay will determine the length of rumble effect.

That is one way.

Another way (untested) is again create the variable then add to blueprint under get, drag of and play haptic effect . Select your haptic effect and assign to the custom event. then call when needed.

Hope this helped
