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]
  • Use the action:

    Move at angle
    Move the object a number of pixels at a given angle in degrees[/code:28sy298i]
    

    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?

    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.
