Can be evaluated for running entity functions - for instance, particles - depending on its visibility. if (!(my.eflags&CLIPPED)) { emit_particles(); } // lite-C 3D Gamestudio A8 Pro AMD FX 8350 4.00 Ghz 16GB RAM Gigabyte GeForce GTX 960 4GB

Hi Progger In minecraft aren't tousends of blocks. the world is splitten in small parts every part is a big mesh(like chunked terrains in A8), so there aren't much rendercalls( and polygons too ). But if ur game isn't a minecraft clone it could be very hard or impossible to make something like this. I think the best way is such a calling system like u said. xxxxxxx Es ist immer wieder erstaunlich, dass Leute die riesen Scripte schreiben die einfachsten sachen nicht k�nnen zb. mich mit SIEBEN x zu schreiben!
