Hi everybody !
How can I, in Solarus, do a transition by pixelisation, or by a circle around the hero, ike alttp, please ?

It will be possible with shaders, in Solarus 1.6

That will be a huge help to quest makers.  Currently the only way to create a transition such as a circle around the hero when he enters/exits a door, or by drawing a "lantern light" around the hero when inside a dark room,  is by using an animated sprite and draw it on the screen when a certain condition has been met, like when the hero touches a sensor.

I know that I'm going to have dark places in my game, so making it easy would be greatly welcomed by me.

Thanks you a lot !

I would like to see all the stuff you can make with shaders. I do not have coding skill, so I might be able to use it?

You can use bsnes shaders.

IMO, no coding skills = you can't do it.
Solution: learn Lua, or find a programmer for your project.
