Frame animation on Firefly primitive: plane example (it can be billboard too)
not sure that windybeardgames would want his art out there - draw me a tree and ill give ya the mfa :P
I see you fixed an odd jitter issue from the other version as well.
I've been wanting to make a grandia-style battle engine for a long time, but a purely topdown perspective does it no justice. Mode 7 didn't work because it was too hard to calculate angles of sprites and there were also a lot of graphical glitches that were just caused by the nature of Mode 7 . . . also the performance issues. P3D might work, but it isn't easy to use imo.
This looks great and is smooth. I will probably end up referencing this example if I ever get to work on this.
