    Zooming techniques

    Hello again!

    I'm looking for various ways of making a zoom-out effect for a top-down space game.

    I know two already;

    1.) Using the Zoom-shader in MMF2 HWA with a zoom factor of 2 to begin with, creating an effect of zooming out when moving towards zoom factor 1.

    2.) Using trigonometry to place all objects according to the center of the screen and scaling accordingly.

    Method 1 is easy and doesn't eat cpu, BUT, since my sprites are really small (24x24, 32x32, etc.) the zoomed in versions look like blurred crayon drawings.
    Method 2 is crisp and clean to watch, but using trig on- and placing 1000~ individual actives every loop eats cpu like candy.

    So, any suggestions on more ways?

    The only other idea I know of is creating the whole thing using the OpenGl extensions, but I'm not well-versed in the code involved, so that would be = abandonware in days.

    Input?

    If you had Flash you could use the Vector object...

    But if I were you I'd have bigger objects so that the zoomed in isn't blurry, and zoom out from there somehow...?

    Re: Zooming techniques

    The problem with using bigger objects is that then you lose the actual effect I'm aiming for with the zooming out, otherwise it'd be the way to go.

    I want the player to be able to get a good overview of a large are around the ship with the zoom. Most gameplay is meant to be zoomed in though, the zoomed out view is mostly for orientation and using more massive long distance weapons.

    I came up with a vague idea of a way to maybe fix my problem. I'll post if it works.

    If anyone else has any idea your welcome to join in.

    I'm pretty sure I've seen an example of this. I think it used the perspective object, maybe the viewport object.

    Re: Zooming techniques

    I'm having the same issue in my game - I want to have the view window zoom out to show more of the frame (for scoping, like you said) when the player presses a button. However, I've already built the entire game up to this point, so I'd prefer not to overhaul the whole game to make this work.

    I tried converting it to HWA to try the zoom-shader, but it's telling me MMF2 HWA can't open because of kcedit.mfx (guessing because I workied on it up to this point using non-HWA so it might not be compatible).

    I tried the viewport and lens objects, but neither pick up anything outside of the window frame when you zoom out. In that sense, they're probably better for zooming in sections than zooming out the whole view.

    I don't need anything fancy, just a quick zoom-out so that the player can see the whole frame in the window at once.

    Thanks!

    Re: Zooming techniques

    kcedit.mfx is the Edit box control, perhaps for some reason your HWA can't open it because it is newer or older than your main MMF2 version?

    I think there is a Zoom example on my website.

    It is incompatible; you need to update your HWA version to the same as your regular MMF2 version.

    Re: Zooming techniques

    Jacob. Who or what are you referring. My MMF2/HWA or my example. Or not referring to me at all.

    I am on 251 on both. I don't have the combined 252 because I am not beta testing.

    Re: Zooming techniques

    Well, Marv, you replied to me, and I replied to ultranovaking about his problem with the extension, and Jacob replied about it being incompatible, I think that people here are just happening to reply to the wrong person.
