To Count Eliminations you would have to have after someone gets Eliminated to Update said Number on said HUD and Replicate it so everyone sees its
Player Character
Variable - Eliminated - Integer
When Actor is Destroy (When Health is 0)
Set Eliminated for the condition of the value (Eliminated - Integer+integer(1) ) then inside the Widget create a binding for the text
CastToPlayerCharacter - Get Eliminated - Connect to Text Out
Get Player Controller
In UEFN there are the Island Settings, which contain the elements for Team Score UI
Further options are available if you use the HUD Controller Device.
In a little rush atm irl, let me know if you need more help with settings and I’ll give you some screenies.
