See under the trees

[BahaFura]

Hi, I want to create a forest which is hidden by the leaves before you enter it, and when you are inside, a circle around you enables you to see under the leaves. Here is exactly what I'm trying to do: http://2.bp.blogspot.com/_Xw6HR3aAZH8/Ra86mR4zvoI/AAAAAAAAAN4/fhCw51rmDNA/s320/tiny%2Bforest2.JPG

I thought I could use layers to do it, but I can't make anything nice. Thanks for any help!

You can do something with layers and PixelShaders.

Make the stump or bark of the tree one active object...leaves another then do this.

If player collides with leaves>make leaves invisible or change the ink effect transparency.
If player isn't (not) colliding with leaves>make leaves visible or change ink effect transparency to 100%

That would work if I did too many active objects of 1x1 pixels for the leaves, but I don't want all the leaves to dissapear, just some part around the the player.

Maybe I could make 4x4 pixels leaves objects, and then depending on the range from the player, change the transparency proportionally, so that a it creates a transparent gradient from where the player is to the other leaves that still hide what's under them.

What I would want is something that when two active objects (the leaves and a circle) are overlapping, then the leaves object gets erased exactly, pixel for pixel, where they are overlapping. But I've never heard of anything like that in MMF, so that's why I'm asking.

As for the layers and the PixelShaders, hum... what are pixel shaders? well, what are they in MMF? I can't find any extension, just a topic with some examples...

Thanks a lot for trying to help!

Hi. Pixel Shaders are used in the HWA verion of MMF2. Download the HWA version and then download the Shaders.

Try using the "Hole" effect
