Hi! i downloaded a character from mixamo running work just fine, but i can’t add a run jump animation (not a jump because this is an endless runner game, so the character don’t stop running)… really, i don’t know how to do it, so please help me, NOTE: i’m 12 years old and i just started learning ue4 yesterday so please express me in detail 
NOTE2: Thanks
So you have 2 animations. 1 For running and 1 for Jumping ?? if you want something like that you need to use an Animation_Blueprint with animation blueprint you can controll your animations. if you want something different you can upload some screenshots and be more detailed so we can understand what do you want.
