Beta 5: [Example] Relative Sliding Movement

[netninja]

Here's just an example I whipped up. I'm sure it will be useful to some of your games/applications.

It would be useful for:

• Controlling the player
• Page sliding
• "Throwing" an object

It's only in one axis at the moment. I plan to expand it to two later, the code would be the same in the Y, unless you would prefer to use angles. It's also easy to add multiple touches at once.

The code isn't really commented because I was just doing it for my own use. I can make it neater and explain it if people want me to. The variables are all stored in the "Movement" object. Most of them are temporary. The ones that should be changed are:

XMoveSpeed: The speed/time it takes the object to move. Higher is slower. Best if it's a multiple of 2. Try 16 for slow. 1 for instant.

XCoefficient: Ratio of pixel movement to finger movement. Value is divided by 100.0 at the start of frame to get a float/percentage. Set this to 200 for 2:1 pixel:finger movement. Play with it, you'll see what it does.

Enjoy.

Forgot to comment the variables in that version.

Variables:
StartX: The start position of the object when the touch starts

StartTX: The start position of the touch

XAmount: The difference from the start touch x and the current touch x

Moving: A flag 0/1 to test if the movement (workaround for the 'quirk' I mentioned on the other thread)

XMoveSpeed: The speed/time it takes the object to move. Higher is slower. Best if it's a multiple of 2. Try 16 for slow. 1 for instant.

XCoefficient: Ratio of pixel movement to finger movement. Value is divided by 100.0 at the start of frame to get a float/percentage. Set this to 200 for 2:1 pixel:finger movement. Play with it, you'll see what it does.

TempX: Where the player would like to move to.

SmoothX: The calculated smoothed out movement using the variables above.
