I don’t think there’s a direct way to store key presses up for later. If there is, I’d be glad to learn about it. 🙂

There a couple of ways to work around that, though.

The first idea that jumps to mind is to “convert” a key press into something more easible storable (like an enum value) and push it into an array of “queued” commands if a command cannot be executed right away. Then when the current action ends, you could get and remove the first element of the array (if it’s non-empty) and, depending on its value (for example using a Switch node), trigger the function the command would have triggered if it had been possible at the time.

If you only have a few highly specific situations where a given action might not be possible at the time but needs to happen later, you could also use _Gate nodes_. In response to the key press, add a Branch. If the action is possible right now, do that. Otherwise if the action will be possible later, _open_ a Gate. When the current action preventing the execution of the command ends, attempt to _enter_ the Gate. This will only execute if the player had pressed the other key earlier. After triggering the action, make sure to _close_ the gate again. You can also _close_ the Gate if the player does something else in the meantime invalidating the second key press.

For combo moves, you could also check out _Animation Montages_. Use _Branch Points_ to handle switching between different animations and _Anim Notifies_ to trigger specific effects depending on which animation is playing (like different amount of damage dealt, stunning the target or knocking the opponent a specified distance).

These are just some ideas off the top of my head. Which one works best really depends on the circumstances of your game. You might end up using a combination of all three or come up with something entirely different.

Good luck!
