Greetings readers, I’m jeffry, I’m new on this forum and i have some questions because my unity is kinda messed up. I’m working on a FPS game and i need to add some weapons, I got like 2 weapons added but the third one i can’t do. THe third weapon is a sniper rifle.
(i cant even let it fire ) i’m new to this , followed like 40 tutorials and i can make a game now. But my problem with the rifle is i cant make it on my Nr.3 key and i cant make it even fire, ( i have all the scripts already but it just wont work. ) My second problem is : I want to build run my game. After i did that and im going to let it run. When it’s running i can online look around, i cant move i cant shoot , but when i play it in the preview it does. My last problem is : I was looking a tutorial where they made robots as enemies, i know how to do that all but when i run the game the robots just fall together and run around killing themselfs ( L.O.L ). Anyone got any ways to solve these problems? i’ll add the code of the sniper here. Thank You!
