Advanced button mapping for multiple keys

[TheRogueMaverickYT]

I have a question related to control mapping. I tried to search for what I was needing for a bit to no avail. Is there a way to have one controller button push two virtual buttons?

I have an (OLD!) Logitech Attack 3 Joystick that I'm using for Mario Kart Wii. I don't need the full suite of buttons of a GameCube controller, so I ended up with 2 free buttons. I want to have one key combine L and Stick Up for fire an item in front with the other being L and Stick Down for rear attacks. This way, I don't mess up my steering with the wide range of movement to aim an item directly.

I am fairly tech-savvy, but uh... the Configure Input screen uses coding, essentially. I haven't done much for programming since high school a good few years ago.  It was mostly Visual BASIC that I grasped. Java wasn't so easy.

If anybody could help me with this, I'd GREATLY appreciate it!

That was one of the resources I checked first. I still couldn't understand it.

If I'm reading this correctly, you want to have an input that has two simultaneous outputs? That's easy! I'll give you a quick walk through.

So first of all, here are the things I'm assuming.

1. You are using the latest dev build of Dolphin. Control mapping has basically been totally redone twice over since 5.0, and it is WAY better now so, use the latest dev build.
2. You have configured the device you wish to use in the main mapping already and it is working, so everything but the combined functions you want are working.
3. You aren't doing multi-device inputs, just the Joystick.

Ok so, the way Dolphin is set up is that we map the outputs, not the inputs. This means that there is no way to select the button on your joystick and have it map to two different outputs. So to get what you want, we have to work backwards from the outputs to the inputs.

Now, here's what you need to do. First up, right click the "L" button in the GameCube mapping, and you'll see the advanced mapping window with your working mapping for the L button. It will be a green letter or text with quotation marks around it. Now, on the right there is a dropdown that says "Operators", click it and select " | Or". Don't use Xor, use Or, if you don't know why then don't worry about it, just, use Or. Now you should see your existing green input with a | to the right of it. Next, in the big input list in the left-center, find the input you want to use for the L combo button (by either scrolling to look for it or clicking detect and then pressing the intended combo button), and click it to highlight it. And finally, on the right side, click Select. You've done it! It may not have the quote marks around it or be green (we should probably make it add those...) but it will still work. Now click OK to return to the main control mapping window.

Let's confirm that it worked. Press the joystick button you have mapped for L the GameCube's L button should light up, now press your L combo button and the GameCube's L button should also light up. Tada!

With that working, what we need to do now is do the same thing for the Control Stick Up. It's the exact same process, so right click Control stick up, add "| Or", now find your L combo key and highlight it, then click Select. With that done, click OK and go back to the main mapping window. If you press the L combo button, now the L button and Control Stick up should light! And if you press the existing L and Control Stick up buttons you mapped previously, they should also still work without any issues.

Now repeat this process with your other planned combo and you should be all set.

Okay I got it so it activates the item when I push the stick up. For reference, I'm playing Mario Kart Wii. But when I push up on the stick, it still drops the banana peel behind me. Sorry if I sound rude, but I'm trying to get the button to accomplish holding up before firing the banana and vice versa for the shells.

Could you post a screenshot of the GameCube controller mapping?

Sure! Here is what I have.

Hmm. You seem to be misunderstanding the difference between L and L Analog. Fortunately Mario Kart Wii doesn't use L Analog at all (or it doesn't use L entirely... I don't want to test it atm) so you don't need to learn the difference, just middle click L Analog and clear that value entirely. ...Or middle click L and assign it to Analog L only, just, whatever the game is looking for. Or to be safe just make L and L Analog have exactly the same inputs, that should cover both scenarios. Just remember that L and L Analog are on the same button on the GameCube Controller, even though they technically have different outputs.

Anyway, you didn't quite get what I said about mapping outputs, not inputs. If you want "Button 11" (hypothetical button for demo purposes) on your controller to activate both the GameCube's Control Stick Up and L buttons at the same time, then you need to do this:

Control Stick Up mapping: Axis Y-|Button 11
Triggers L: Button 2|Button 11
(and just to be safe) Triggers L-analog: Button 2|Button 11

With this, when you press "Button 11" both the Control Stick Up and L Trigger outputs will be sent at the same time.

You can just repeat the same for throwing it back using "Button 12" (another demo button) by mapping it to Trigger L and Control Stick Down via "| Or".

Okay, I've copied what you showed above. I just wanted to test with one input to test. But it didn't seem to work still. Is it because I had the Button 2 and Button 10 swapped? Button 2 is the one that I want the combo on.

[MayImilae]

If you want the combo on button 2, then yea, you have them swapped. Button 2 should be in Control Stick Up, not Button 10.
