Im making an RPC function that can hold actions. Such as dodge, sprint, attack, etc. I’ve made an enum that is a bitmask to conserve memory and ive made a new player controller so everyone could have it and so that my actor file isnt so clogged. Everything would be in the playercontroller file. So i did all this and so far im starting off with what should be the easiest… “sprint” i created the start sprint in my character function and i made a pointer to my player controller -which im starting to think i should just put the startsprint input in the player controller too, but we’ll see to whoever responds to this- and im either getting nothing my character stays walking or i get that my characrter tries to start running but the sever isnt allowing the character to change run speeds so its locking it at walk and all i see is the client attempting to run but not on the server. (ill link code and what not). Anyway, ive been trying to get used to bitmasks and bitflags and i thought i had it, maybe im doing something wrong. I thought i had everything right, but clearly sometihing is up! lol. I think it has something to do with the pointers or maybe the flags arent turning on correctly but we will see. Any help is appreciated!
ill have a video when it uploads. As of now, here is the code… the important parts.
UPDATE : video link
