thankyou

why does it skip to the next column?

Let's say that the width of the plane is 64 tiles. The size of a tile ID in bytes is 2 bytes, so the stride of the plane would be 128 bytes. Setting the auto-increment value to that would make it so that when you write a tile ID, it will increment the VRAM address by that amount automatically...

.DrawLeft1: move.l (a2)+,(a1) ; Draw column tile dbf d0,.DrawLeft1 ; Loop until section is drawn would this be drawing a tile directly underneath the one above?

thankyou!!

does "draw column 2" and "flush column" both work toggether to draw a column of new tile data or is it just "drawcolumn 2" or just "flush column" ?

what do you mean by flushed? and which part of the code do they actually get drawn?

DrawColumn2: move.w cameraY.w,d1 ; Draw from the top of the camera andi.w #$FFF0,d1 subi.w #16,d1 move.w d1,d2 ; Construct VDP command from camera position andi.w #$F0,d2 ; (y & $F0) * 16 lsl.w #4,d2 move.w...

Thankyou!! This is going to help me so much and also cool images i used genskmod so see the streaming in the plane explorer :D

if you could do that that would be great!! :D

i saw i youtube description and it said something like this: new columns and/or rows get drawn over old ones. The tiles are 16x16 pixels, so two rows or columns have to be updated at a time. This is done using a temporary buffer which gets populated with the tile data and is then updated using...

i t i tried coding the streaming system but i did not know where to start where do you think would be good to start?

thankyou:D

so i was looking around for some piece of code to get started coding for the Sega mega drive so i found a really good sample but the only problem was i did not know how to build it but i eventually found out i changed the maps and stuff

so i would need to construct a vdp write to write to an appropriate portion of the plane and then set the auto increment to increment the stride of the plane is there a mode for incrementing a stride of the plane?
