Clipping and Masks - A workaround (vide)

OZApps

Here is a work in progress about having a mask with Gideros, you can see the mask move displaying portions of the image behind.

Hmm, Id say this is a shape with transformed background and synced with moving.
Which is actually a great hack to do and this one particularly looks awesome

OZApps

No, it is the mask object that is moved using setPosition

I was asking Atilim if we could fill using textureRegions which could have been the way to do things however even that would take up processing cycles.

OZApps

Here's a follow-up to demonstrate how this is achieve (if it can be seen/understood)

OZApps

and this is the code to move the mask

local cx, cy = 0,0 local xDir, yDir = 1, 1 local wd, ht = 200, 70 local x, y = 0, 0   setMask(x,y,wd,ht) --> This is where the magic happens   local speed = 3   function move() cx = cx + speed * xDir if cx > _W-wd or cx <= -x then xDir = -xDir end cy = cy + speed * yDir if cy > _H-ht or cy <= -y then yDir = -yDir end   arrow:setPosition(cx, cy) end   stage:addEventListener(Event.ENTER_FRAME, move)

hnim

add some moving for more fun (if i'm right ) )

Can you blur the edges? Thinking about a torch light in a cavern...

I think, you have a big white bitmap ,which has a empty rectangular , in front of the background picture. If it is not my opinion will also work
Good job.

Now I feel, like there's some kind of hidden API feature, I'm not aware of

OZApps

Let's hope @Atilim now shows us how he does it with a new release....

@ar2rsawseen, yep it is a secret API and in my case not a Bitmap image. It is dynamically created. This came into being as a tablelist view or native controls required clipping/masks or GL_SCISSOR but...

Have you seen Helsings fire? The ray casting, I think I saw some samples for Flash that created light or shadows using ray casting. There was another articles that used Ray casting to automatically steer a vehicle on a race track (looked like a spider with many legs) Will give ray casting a go and see how it performs.
