Screen rotation

[uberphear]

Hi, I have read some topics here about rotating actors, but noticed that they most (all?) suggest that it is necessary to create an animation. My problem is slightly different:

I have a ball, which is "falling" (suffering y velocity -) towards the bottom of the screen. I have an actor which I tile to create a path/maze for the ball, but I wish to rotate the screen (or the actor with the tiles) so it is possible to rotate the screen with left/right arrow keys to allow the ball around a corner. Effectively, it would be like one of those 'tilting maze' games, except 2D and with rotation. I've tried using 'angle' but it doesn't do anything useful - any help would be greatly appreciated

If any of you have played On the Ball on the SNES, the effect I'm after is just like that.

You can make an animation for the whole level with frames for each amount of rotation. Create a real variable: ang, and add keydown events to increase it or decrease it. On draw actor:

Code: Select all

if(ang>=360)
{
    ang-=360;
}
if(ang<0)
{
    ang+=360;
}
animpos=(ang/360)*nframes;

The hard part is rotationg around a particular location.
