Does anyone have any good information for handling multiple points for any of the following situations? [Particularly for Android, unless it isn't any different from iOS ]
The above diagram basically explains what I am talking about. I usually refer to the reference and any available tutorials when it comes to this learning something new, but I haven't been able to find a tutorial for Android and I'm not to sure where to look for all the available functions/classes for Android. I managed to find this in the reference, but I'm not to sure how to use it with multiple points.
- Slash across an object [Similar to the game Fruit Slice]
- Moving an object from point 1 to point 2 [Or like a toss effect]
- Zoom in/out screen pinch
- Drawing an ellipse and counting them.
- Drawing/tracing multiple points [In a particular order]
A code based implementation would be nice, I want to know the complexity of doing it from scratch before buying pre-existing packages.
