Joystick(s) logic of battle-rage¶

The joystick plan:¶

battle-rage joystick usage¶

For playing battle-rage you only need the the 4 buttons A, B, Y and Y and a directional pad (stick).

The button at the top of the joystick (RF, RB, LF, LB) aren’t used.

You can use the digital stick (directional pad), which is recommended, as well as the analogical stick.

warning: I can’t guarantee you that you can use twice stick at the same time once your joystick configured.

battle-rage and his joystick rules¶

battle-rage has some rules for playing with the joystick.

According to the fact that you have 2 hands and 2 foots (exclude for the physic handicap).

battle-rage follow the same logic for the joystick buttons logic:

The back hand from your fighter is activate by pressing the A button from the joystick.

The front hand from your fighter is activate by pressing the X button from the joystick.

The front foot from your fighter is activate by pressing the B button from the joystick.

The back foot from your fighter is activate by pressing the Y button from the joystick.

note: You can sea that like a cross which X axis is are the foots and the Y axis the hands.

You can use combinations by adding a direction from the directional keypad to the used button.

This will generate different kicks for every combination.

Finally all combination make sens, per example:

Pressing the Up arrow and an hand button will produce an uppercut,

and pressing the :Back arrow and a foot kick will produce a return foot kick.

Warning

because nothing is perfect it can happen that a combination don’t really

represent what it should like explain above.

But I guarantee that it really doesn’t happen often and that the replacement is near from your expecting.

And some kicks have fallbacks: this mean that 2 differents combination can give the same kick: not often.

All according the fighter.

note: Because it’s easier to press a button instead of using a combination the combinations inflict more damage.

Note

This logic is follow for every joystick model since you have to configure your joystick first.

But you can reconfigure your joystick if you make a mistake during the configuration phase.

The different joysticks models handling¶

battle-rage doesn’t claim to take in charge every different joystick model of the world but:

Note

battle-rage does the best for taking in charge the most of different joystick models.

And you must pass through a joystick configuration phase, which is oblige,

every time you plug a new joystick model.

Not every time you plug your(s) joystick to play the game !

warning: To know that every time you plug a new joystick model you will have to configure it.

That’s better for all: the game logic, you, conversation about battle rage,...

Because it permit to set a precise combination set, not in according differents joysticks models mess, but according to the game.

Advice:¶

You must better plug the joystick before starting the game.

Else you will be notify about the problem and be invited to plug a joystick before really starting the game.

And if you plan to play with 2 users plug 2 joystick before gaming.

But you if you don’t have plug 2 joysticks you will be invited to do so...

Sorry but my joystick handler doesn’t handle the plug-in plug-off of joysticks,

so the free hot plug of joystick(s) is not permit with battle-rage.

If the joystick configuration fail.¶

If you have bad luck and your joystick model is really not compatible with battle rage, havoc.

Else, if you made an error, you can try to reconfigure your joystick again by using the configure joystick menu item.

note: Sea the technical note for further informations.

Technical notes about joystick handle.¶

Internally battle-rage highly suppose that the buttons A, B, X and Y have all a value comprise between included [0-3] like the most joysticks does.

Internally battle-rage suppose that directional pad is implemented as 2 axis (B and Y for the X axis and A and X for the Y axis).

But you can predict nor the SDL2: if an axis number will be the X or the Y but most common joystick use 0 for X and 1 for Y...

But the sticks: analogical and digital are taking in charge, because with battle-rage you must configure you joystick the first time you plug it.

And the big problem is that some joystick doesn’t respect at all this rules.

I can only test this values which are right for my test joysticks (2 joysticks which works differently).

So if your joystick work otherwise than with this values for this set of buttons or axis it won’t work at all !

This fact is coming from that I use an Input_Handler written by Shaun Mitchell, for his book SDL Game Development (june 2013) [Packt Publishing].

I enhance this Input_Handler to take in charge the most of joystick possible: The most common.

Even if the base joystick for Shaun Mitchell (an X Box 360 joystick) won’t work with battle rage because of the fail of one axe.

But you can play battle-rage with an X Box 360 joystick but the Y axis won’t work !

note: Great thanks to Shaun Mitchell for his book and code writing and his code.
