What is the right way to zoom out from a scene view?

Solar2D General Questions/Discussion

Hey there,

I have a scene where my gameplay happens. I’m looking for a way to slowly ‘zoom-out’ so more and more space becomes visible as the time passes. But I want the HUD and some other elements to stay the same. It’s like the mouse wheel functionality in top-down games.

I tried to do it with sticking everything to display groups and transitioning xScale, yScale. It works visually of course but game functionality screws up. For example I have a spawner that spawns some objects, its graphics gets scaled but spawner still spawns the objects from its original position, not the new scaled position…

Do I need to keep track of every X, Y position I’m using during gameplay and transition them too? (Which is probably possible but too hard for me since I use a lot of touch events for aiming and path creating etc.) Or is there an easier way to achieve this? Please please say yes :stuck_out_tongue:

I’m looking forward for your answers, thanks in advance! :slight_smile:

I’m coming from GameSalad and they had camera.width and camera.height and you simply changed them. For example from 320x480 to 640x960 to make everything smaller.

If Corona has something like this, I can use it and change the size of the HUD elements accordingly to compensate.

Anyone?

I’ll shamelessly bump this once more because I can’t continue working on it without knowing this.
