Re: DMA transfer to CRAM visible however the screen is off.

Actually I did intend to display an "almost" direct color image. And it's almost successful. It's possible to reload 48 colors per screen line thus you have 12 dynamic + 4 static colors per palette. But it doesn't help too much as long as you can't overlap those colors. Each 16 colors are bounded by...

I guess I confused something and didn't understand you right.

Re: DMA transfer to CRAM visible however the screen is off.

A VDP palette has 16 colors.
You can't use 56+8 colors.

If you make a heap of layers than you should transfer a lot of image index data for each layer.
VDP barely can transfer them for one single layer.

Re: DMA transfer to CRAM visible however the screen is off.

Even he shows such zoomed images I can see clearly those damned columns. The most important to know is that it's possible to sync. But it doesn't help too much. Personally for me those wide columns destroy everything. I could ignore 2x1 sized pixels. But I can't ignore those wide columns. They just ...

Re: DMA transfer to CRAM visible however the screen is off.

An interesting feeling to know now how it's easy to sync VDP...
It's really strange they couldn't do that in 1993.
No magic. Just overload VDP and make a fine pause after that.

Re: Please help decide on projection

The most interesting that human perception almost doesn't notice that feature. At least in the times when SC1 was very popular I personally had never noticed that. I felt a bit that something was wrong and strange but that's was a very slight feeling. The left fake-projection causes to me much more ...

Re: Please help decide on projection

StarCraft 1 uses isometric visualization and "plain" 2D physics. For example if you command two the same units to go horizontally and vertically they will do that with the same speed. If the physics would be really isometric vertical moves would be twice slower for example as in another less popular...

Re: Please help decide on projection

Yes I am aware the left is not an orthogonal projection. They call it "oblique" and "military" particularly. The right is almost isometric. Currently the most probable scheme is really "both" as cero "suggested". Visual appearance of the right one and "physical" part of the left one. It's surprising...

Re: Please help decide on projection

True. It produces an easier-to-see playfield. But my visual perception more likes the right projection. The left one looks like a bit weird to me. Actually that's the problem to decide on: left one: better playfield + worse appearance vs. right one: worse playfield + better appearance The left one h...

Re: Strategies for collisions with background

The simplest way to have obstacle bit-map. 0 for free space and 1 for obstacle. Shift position coordinates of sprite for example >>3 or >>4 (depending on what background cell size you have) and get cell of the obstacle map. Something more "clever" will be more context-dependent. If you would like to...
