Questions on Deadlock

Hopefully Dan will chime in. Very Happy

But I was wondering a few things. I will try to break the game down in more detail later but I thought I would ask. (Also, insomnia kicking in so please excuse any typos)

1) How where the raster color changes coded in the map? For example, some levels have the same chars but change colors. I know this is a simple raster split but how would that be stored in the map data?

2) This appears to be multi-color bitmap mode. Is that correct?

3) How many sprites are used in the main character? BTW, the gun going behind the left hand when facing left totally gives me a hardon. LOL. (meaning good job).

Thanks!

nah, thats characters and colour ram i would think.

the "plane" is done using 2 greys as Multicolours, black as background and the detail colours as colour ram.

you can usually tell bitmapped graphics a mile off because they will use 3 colours from upper 8 together somewhere on the screen and character set & colour ram can't do that.

Sorry mate I completely missed this post!

1) for every room we stored a table of 3 colours for each 5-6 chars (might have been for each vertical "block" which were 2x5 chars IIRC)
2) STE is right, its just using color mode, that with the splits gives a more colorful appearence Smile

3) 4 (head,torso,gun and legs). The head and legs shared the same hardware sprite. The sprites for the legs were also being flipped horizontally on the fly to save sprite image space Smile

Yeah the changing of which sprite was used for the gun/torso was a simple trick Smile

and kept Rob happy, he didn't want it to appear the player's character was changing their handedness Very Happy

Cheers

Dan
