How to make zoom in and zoom out with a slider on minimap?

Question

Hi

I am a newbie with Unity3d, managed to create a minimap with this minimap tutorial.

I would like to add zoom in/out functionality within my minimap controlled by a horizontal slider. May I know how can I create the zoom scripting for the minimap (GUIStyle) to map to the horizontal slider value?

Thanks.

I only skimmed the tutorial, but it looks like 'sceneWidth' and 'sceneHeight' are the variables that determine the size of the area shown by the map. If that is the case, then you'll want to tie these variables (or, more likely, a single 'scene size' variable) to the slider, e.g.:

sceneSize = GUI.HorizontalSlider(..., sceneSize, minSceneSize, maxSceneSize);
