Re: [Adonthell-devel] Rendering, for the 1000st time

[jasper van der jeugt]

Hello,

I haven't quite been involved in Adonthell development, but here is the main 
algorithm I use in my RPG engine for drawing:

- For each object keep a list of colliding objects that are below or behind 
this object. (Speed this up by only calculating this list when an object moves.)
- All drawable objects have a label "drawn". Start by setting all these labels 
to "false".
- Now, for all entities in the map:
    * If this entity's label "drawn" is true, skip.
    * For all objects in the list, draw.
    * Set "drawn" to true.

That did the trick for me (and seemed to work for large objects, too), hope 
this helps.

PS. This way, tiles are considered entities as well.
