Hello guys, i have a problem, in my game i have a gun, gun has a muzzle, I need the bullet to spawn from the muzzle, it works correctly only when i tap shoot button many times, but if i hold the button, the muzzle returns to location like if it in editor, i dont know how it works, because i dont change muzzle transform, help pls with this, thanks in advance ![351592-screenshot-1303.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/8/0/7/8070db115f9110f9fdc147c44af6a5b5c51b420d.png) ![351593-screenshot-1304.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/2/9/629f0acae2f4a972470a23a4ae98c26368231f64.png) alt text ![351595-screenshot-1305.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/5/c/b5cbc48cc86803a6995f3d0cab6932051a088d1e.png) ![351596-screenshot-1306.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/c/0/2/c0222b3deaef283eedfd87d2879d4b2e7e3d92b5.jpeg) ![351597-screenshot-1307.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/0/1/a/01a66b05f6a87064634d716afe80d1f48a5ac96a.jpeg) on last picture the player is turned to -180 degrees, but print string returns zero rotation, it impossible because spawned gun is attached to player and become a child to player, just like muzzle is child to gun, so if player turn to -180 deg then muzzle must turn -180, but if hold the button it returns to zero rotation and different location then actual muzzle ---

I don’t know exaclty what the problem is, but I see two things that might need attention: 1. Get all actors of class on tick!? How many are there? You don’t need to cast, because it’s already the right class of object ( hence the blue warning ). Can you just get it once and set the variable? 2. Here ![351605-screenshot-1.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/7/e/17e37ec8659109b7d9698e4582f84d0af16fce4f.jpeg) It will open the gate, then call 1 in the seq, and not wait for any time before calling 2. Delay is a latency node ( hence the little clock in the corner ). That means execution carries on, the system will not wait for it. ---

I know how delay works, I dont understand what kind of mistake I made in this code. ---

Sorry 🙂 The sequence node won’t wait for the delay. The moment pin 1 has started running, pin 2 will run, and the delay will have no effect. More this kind of thing ![351642-screenshot-1.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/8/b/8/8b8aaabbd5c903aa12e44738d24feb44a21ac322.jpeg) But I also suspect you’ll a DoOnce in there somewhere too. ---
