Make object invisible gradually
Hi guys, I´m trying to do something like Portal, but not the two way. just one portal, and what pass through it disapear, like going to another dimention. if i´m not clear, a good exemple is the videoclip Gnarls Barkley - Going On (Official) http://www.youtube.com/watch?v=ENE1eWtW7e8 (2:28). Thanks for the help.
Is your game 2D? In the linked video, the portal is seen from its side, and people entering it from the left don't appear on the right side:
A simple way to achieve this effect is by using a depth mask on the right side: the depth mask is an object rendered with a special shader that doesn't render a single pixel, just sets the depth buffer as if it was actually rendered - this obscures anything that passes behind the mask. You must set the rendering order so that the mask is rendered after the background and before the "obscureable" objects. Take a look at this question, where the shader and the code that sets the rendering order are posted.
