Camera zoom in/out

BeyondtheTech

For the camera being able to zoom in and out of the entire scene at any magnification would enhance gameplay. Tower defense games could zoom into a particular action onscreen, or if two actors pull far away from each other, the camera can zoom out to keep both of them in view while the user is able to see the whole game area.

Agreed

You would need different bitmaps for different zooms, rasters and zooms don't go well together.

BeyondtheTech

I don't think so, as Torque 2D does this well. All the sprites look fine when you zoom in and out.

it probably depends on the sampling method used. for what we are doing, just using nearest neighbor sampling would give us snappy, yet expectedly crappy magnification.

On a side note: can GameSalad Zoom in and out of a scene, stopping at a define zoom amount, using pinch-like gestures on the iPhone? Does anyone know where there would be any documentation on how to set this up perhaps, I dont mind the nearest neighbor sampling in this case(though something like bilinear would be great).

BarkBarkCo

you should be able to check for 2 touches and track their magnitude; if it shrinks, it's a pinch, if it grows, it's not.

I've read that GameSalad cant zoom in and out with the Camera, only Pan. Is this true?
thanks BarkBark :-)

BarkBarkCo

as a work around you could manage the size and position of all of your actors and shrink and grow them to make it look like zoom in/out...

that's not something I would want to do on a large scale.

devx

ouch this is something I'd like in most of the projects I'm starting that are the "larger projects" planned for GameSalad. Is there any word on a camera zoom being added to GameSalad anytime soon? I would almost buy iTorque just for this type feature for the projects that call for it. Thanks for the heads up on iTorque BeyondtheTech, time to research iTorque for me, ugh.

You can zoom the camera, just change the size of the camera with the related scene attributes.

Photics is right you can zoom the camera but not in an easy way. You have to drop an actor to the scene and modify that instance to get access to the camera attributes of the scene. A Zoom Scene behavior that could do this would be great.
