how would you want it, like an animation glow or just a static texture?
if texture you can do/bake that glow in your favorite authoring tool/s.
if by animation like dimming and glowing,
2 ways i think(im no expert just so you know...),
1: animate it through your authoring tool and make a spritesheet so you can animate it in cocos2dx using frame by frame animation or,
2: you can use shaders if you know openGL, its much more challenging bec. of the low level nitty gritty stuff but the effects you can do are amazing.
