Fade Colors on a Polygon using the Game Loop

Posted by in Software, Tutorial

One of the features I need to implement is to smoothly change the fill/stroke color of a polygon, like this: A manual approach In order to better understand the mechanics, I built my own fading PoC. First, one would need to build the polygon:

In this particular case, I have a text field and a rounded rectangle beneath it. the hud group contains both in the right order. Once the components have been created, we build the function to be called each frame:

Antialias a Polygon with Corona SDK

Posted by in Software, Tutorial

The other day I figured I needed to draw a polygon in Corona SDK. With display.newPolygon(...), the job is extremely easy and a result like (apologies for the JPEG artefacts): It is obvious that in non retina cases, one can see the aliasing of the polygon’s edges. Hence I’ve thought and searched of various ways to provide the polygons with antialiasing. The sum of solutions I found is: Find a flag to enable antialiasing for a polygon Use effects to perform e.g. a blur or a glow and adapt it…read more
