How do I find "most recent key down"?

Hi all,

I am trying to create a nice character movement system and I am employing the 8 direction behaviour (only using 4-directions) to do so.

How I have it working is when an arrow key is down, a boolean is set to true which moves the character in the corresponding direction. So "right arrow key down" sets "IsRight" to "True" and the player moves right.

The problem is when I am holding the right arrow key, then hold down the up arrow key (while still holding the right arrow key), the player just keeps moving right because this boolean was set first.

What I would like to do is only set the boolean of "most recent key down" to true as I think this will solve my problem. Is there a way to do this?

(By the way I have tried setting the boolean on key-pressed but I need to set it on key-down for several reasons.)

the.sand Could you explain a little more what you are trying to achieve? It sounds like you are trying to recreate the already built in movement?

So "right arrow key down" sets "IsRight" to "True" and the player moves right.

The 8-direction behaviour will already move the player right when the right arrow key is pressed by default.

calminthenight The built in movement controls don't allow for overriding one direction when another is pressed in the way the OP describes. If you try it you will see, that up and down will override left and right but left and right won't override up and down. Also, opposing directions cancel each other out. The OP wants the most recent pressed directional key to move the character even if another key is still pressed.

Thanks so much for your response!

An array is more complex than I hoped but if it works it works!

I will look into it.

Thanks again!

the.sand, Don't think of it as an array. Think of it as a stack. You are adding and removing actions from the stack. Only the action on top of the stack is active. The others activate as the top action is removed and the next is uncovered.

Also, if you do take a look at the example by calminthenight, you will notice without the stack, more events and variables are required just to get 2 directions to work. To get the other 2 directions, you would have to double both the variables and events. That makes the code more difficult to work with and debug when something goes wrong. It is a fine example if you don't want to make use of the stack but, you can see the event sheet can very quickly become hard to follow.

Thank you both for your help!

I will look into both solutions and see which ones works best (and which one I am able to program myself).

Thanks again for your time and effort!
