2.5D engine

just want to share: https://github.com/untoxa/ISOEngine

something similar to filmation engine, but unfortunately not that fast. but if you place not many objects into the scene, it works reasonably well.

if somebody wants to make a game from this - welcome.

Wow, that's pretty impressive work. It manages heights and hides caracter when behind an object quite well.

Re: 2.5D engine

I made some last-minute enhancements, you can draw the global maps in the text editor now, no need to calculate the links between the rooms. Like this:

Code:

0=01..
1=2345
2=.A.6
3=.987

where 0,1,2..A are the ID's of the rooms and the dots (or any symbol except space which is not defined as a room ID) are NULL's

Re: 2.5D engine

This is cool!
The code and image data size in the ROM appear to be quite compact.

A video for folks:

Re: 2.5D engine

Please do!

Zalo once posted pix for a ROM I shared in a forum thread. It made me realize how much more visuals or a short clip can convey about a game/etc.
