How do you make an image rotate using Pic.Rotate and mouse controls?

[mobin12]

What is it you are trying to achieve?
Want the image to rotate with the mouses position


What is the problem you are having?
can't get the image to rotate using the mouse

Turing:

setscreen ("graphics:450;300,nobuttonbar,offscreenonly") var player : array 1 .. 2 of int player (1) := 225 player (2) := 150 var chars : array char of boolean %Mouse Controls var mx, my, mb : int %Picture File var PlayerImage : int := Pic.FileNew ("Player.jpg") loop     Pic.Draw (PlayerImage, player (1), player (2), picMerge)     Input.KeyDown (chars)     if chars ('w') and player (2) < 282 then         player (2) := player (2) + 1     end if     if chars ('s') and player (2) > 17 then         player (2) := player (2) - 1     end if     if chars ('a') and player (1) > 17 then         player (1) := player (1) - 1     end if     if chars ('d') and player (1) < 432 then         player (1) := player (1) + 1     end if     View.Update     Time.Delay (5)     cls end loop

Please specify what version of Turing you are using
Turing 1.4.1

What have you tried? There's no evidence in the code you posted that you have tried anything.

Read the documentation on Mouse.Where and Pic.Rotate if you don't know where to start. Also, you will need some understanding of trigonometry (nothing too complicated though).

I know trigonometry but i dont know how i would use it here.

You need to determine the angle that you need to rotate the picture. The x and y of your mouse, minus the x and y of the picture, makes a nice little triangle

i dont understand. that is only two points thats not a triangle.

That should help you[/img]

i cant see the image

It's odd that you can't see the picture, here's my attempt at representing it in in text. Picture the '/' as a diagonal line and the 'v' and '^' as arrows.

code:

v (x, y) of mouse                                         /|                                       /  |                                     /    |                                   /      | <- Length is difference between the y's                                 /        |                               /         _|                             /__________|_| <- Right angle        (x, y) of character ^                                    ^ Length is difference between the x's

You need to look at your game like it's a cartesian plane (which it is). Draw things like this out on a sheet of graph paper, and figure it out.
