How do I move the object exactly at angle of analog stick?

Hi,

To be more precise, I have a cursor controlled by analog stick. Right now it can move in 8 directions, but I'd like to make it turning smoothly. What I'm after is moving the object at exact angle of the angle of right analog stick. Any clue how can I do that? Thanks

Use the action:

Move at angle
Move the object a number of pixels at a given angle in degrees[/code:j92xkjfx]

Thanks, ut that's not what I'm after as this is what I'm doing right now, and only have 8 direction ( and I don't fancy manually creating more ). Instead I'm looking for a solution to get angle of the stick, so it moves always at exact angle f the stick, so you can rotate it with stick.

What is your stick? Is it a controller's analog stick (gamepad object), or did you create a touchscreen analog stick with sprites?

The formula for getting angle in degrees from coordinates is atan(changeinY/changeinX)

If you are making your own touch analog stick - compare stick's current position to the origin position to get change in Y and change in X, use the formula to get your angle from origin, and then use Move At Angle.

I use xbox gamepad. How would you do that with it?

Here is the manual entry for gamepad - https://www.scirra.com/manual/143/gamepad

I think what you are looking for is the following expression:

[quote:1d48ezpy]Axis(Gamepad, Index)

Retrieve the current position of an analog joystick on a specific gamepad. Index specifies left analog X and Y or right analog X and Y axes, subject to Key mapping. Axes range from -100 to 100. Axis values within the Analog deadzone are returned as 0.

So use this to get X and Y values that you can use in the arctangent formula.

Ok, will give it a try mate. Thanks

Any clue what index right stick axes are?

Ashley, sorry, but could you help as this is really complicated to me. How can I get a cursor to follow 1:1 the right analog stick on 360 controler? What I'm after is moving the object at exact angle of the angle of right analog stick.

Hi Megatronx, Is something like this what you are looking for?

https://www.dropbox.com/s/qf88r9zb2bfwn24/mouse_sustitution.capx?dl=0[/code:2mlr4vg8]

Basically you create a second "mouse", if the real mouse is still visible I guess you could make "at the start of layout" > mouse > Set cursor style > none.

That way the mouse would be invisible when it overlaps the game window.
I hope it helps.

No. I have that already. What I'm after is moving the object at exact angle of the angle of right analog stick. So if I press the stick at 78 degrees, that will be the angle the object moves.

Any clue what index right stick axes are?

I haven't used this object myself yet, but you could test this pretty quickly. I've made a capx for you. I hope it works, I can't check myself as I don't have a gamepad hooked up.

The reason it probably isn't specified is because there are many different gamepads out there, each with different amounts of input axes/mappings.

Thx, but don't have installed latest beta.

Probably to get the angle of the right stick it would be:

angle(0,0,gampad.axis(0,2),gamepad.axis(0,3))

Get the input for both the horizontal and vertical axes of the stick you want.

angle = arcTan( stickY/stickX )

moveVector( cos(angle), sin(angle) )

Do whatever to make the code work. Using the arctangent from the stick data will get you the true angle, and using cosine and sine as the X/Y movement increments will ensure it moves in the correct direction. Increment at whatever units you're using.

Hopefully that helps.
