Draw a circle around the player using Canvas [SOLVED]

[Hblade]

Hi, I want to make a room in my game where it's pitch black and you have a light that surrounds the player (This is done by a canvas covering the screen and its drawing solid black, but then uses some.. well, the question of this topic ) The plan is, the circle will start bright in the center (about 32x32 with complete opacity), then get darker as it increases in distance. Any idea how to do this?

Example:

EDIT:
Solved and working amazingly

If this can't be done I have another plan.

Doing this with the canvas would be really slow I think. You might be better off making a sprite that is a light (like you have in your example) with a large black background and have it follower the player, if you get what I mean.

EDIT: Saw your edit. What did you end up doing?

[Hblade]

It was frightenly slow, so I used a gigantic image and placed it correctly. which was what you said Check out the game demos, Sky made a nice canvas effect for lighting. It's very interesting to say the least. I love it. It's in my realime lighting thingy.

I ended up making an Actor called "Darkness", and changed the transparency a bit.

like this

it might be too large, if so I can design you one.

Could you make me one in Iphone res. (480x320(Rotated left))?

[Hblade]

The thing is ripper, it has to be like 2.5 times larger than the original res, otherwise the black-area will vanish if the player is in a corner (Or the edge of the screen if your at the last part of the map)

So, whats the max resolution image an Iphone can handle?

I think it's 2048x2048, or 1024x1024, I forgot. Probably the smaller one
