not sure how to do that on cocos2d-x

CCTint is just change vertex color not ccsprite texture color.
If you use cocos2dx v1.x , refer to link site.

If you use cocos2dx v2.x, use custom shader.

try using the following function:-

ccBlendFunc brightnessBlend;
brightnessBlend.src = GL_SRC_ALPHA;
brightnessBlend.dst = GL_ONE;

sprite->setBlendFunc(brightnessBlend);

Paras, do you need to call something else after that ?
It does nothing.

There is no duration for some action there too…

#6 
sprite->setBlendFunc((ccBlendFunc) { GL_SRC_ALPHA, GL_ONE });

Maybe another way to achieve the same thing:
_sprite->setColor(ccc3(r, g, b));

This post seems to be old is there any new solution to this ?

@tink3r_t The only way I managed to do this was with a custom shader, didn’t find any built-in functionality to make it work.
