how do u rotate objects in vb.net

[MiG-]

im making a program and i need 2 know if there is any way of making a object rotate, such as a label, on a keypress. i can do keypresses, but i was told that objects can only be rotated by a lot of messing about. is this true ?

If you mean rotated in the sense of tilting it on an angle, i don't believe that's possible, and it's not called an Object, not correct to call it that, i mean it essentially sort of is... but it's called a Control. You can position the controls in different locations, but rotating it in an angle would be hard, it depends what you want to do , have text drawn on a slanted angle? You might want to do some custom drawing.

i wanna spin it around, its for a racing type gam3 or something similar, i know vb.net aint made for games but just interested if its possible.

I think it would be better to draw it, especially if it's just a little game.

how would i do it then, so when i press down on a key, it starts to rotate the object.

e.g. if e.keycode = keys.right then

object.rotate ??

i know object.rotate dont exist but i need help plz.

You would probably have to use GDI+ to draw the control yourself. I don't know where to begin though :s

i dont wanna mess about with complicated techniques. i think i'll give it a miss. :yes:

Maybe this is what you are looking for:

Rotate an image in VB .NET using DrawImage

Here's another:

Rotating Picturebox Control

This are images being rotated though, don't know how suitable that is for your purpose....

Well, you have to 2 options if you are going to rotate text ONLY:

A: you can use this code to make a text rotated ("TEXT ROTATED")

 ? ?Static AngDegree As Long 

 ? ?' Draw the text with angle EX: (45, 45).
 ? ? Dim graphics_path As New GraphicsPath(Drawing.Drawing2D.FillMode.Winding)
 ? ?graphics_path.AddString("TEXT ROTATED", New FontFamily("Tahoma"), ?FontStyle.Bold, 20, New Point(45, 45), StringFormat.GenericDefault)

 ? ?' rotating (45, 45).
 ? ?Dim rotation_matrix As New Matrix()
 ? ?AngDegree += 20
 ? ?rotation_matrix.RotateAt(angle, New PointF(45, 45))

 ? ?' Transforming.
 ? ?graphics_path.Transform(rotation_matrix)

 ? ?' Final View after rotating
 ? CreateGraphics.Clear(Me.BackColor)
 ? CreateGraphics.FillPath(Brushes.Black, graphics_path)
 ? ?End With

B: Build your control by using "USER CONTROL" and attaching to it the "label object" and by doing some fucntion and property for rotation.

upgrade you control properties by replacing font,size, angles and fill mode with variables which is controlled "control properties"

Note : Most of fonts works with this mode "FillMode.Winding"

Option B is cool but if you tried to move the text by using a timer, it will be flickering or may not see the text at all.
