For a menu please remember that you want to have two screens / major situations in draw() now: the game and the menu

You don’t want to mix them.

So start by saying boolean menu = true; before setup().

In draw check

if(menu) {
    // show menu
    .......
    ......
}
// -----------
else {
   // show game, guns.... what you have in draw() now
   ..... 
   ...
}//else

Nothing outside these lines is allowed in draw() (because it wouldn’t know to which state it belongs) except background().

The key checking: do it separately for both screens within the brackets {...}.

Remark

When you have more screens than 2, like with a game over screen, please make menu to an int named state which can be 0, 1, 2… so each state has a number.

As soon as user pressed a key in menu say menu = false;

Then you are in game mode

when you use keyPressed as a var, each key can be registered multiple times by processing. When you use a function keyPressed() and evaluate the key there, each key is registered only once. That would be better for the menu maybe.
