shooting game sprites

[berzerze]

hello
I drew some sprites and backrounds for my imaginary Mega Drive shooting game. The screenshots are collected with photoshop. Some sprites I made ​​using the Eggman demo and a flash card onto the Mega Drive, see bin-data. Everything is drawn in MD-color palettes. Unfortunately, I have no idea about programming, although I was able to learn a lot about the graphic representation by Imagenesis and Basiegaxorz. Maybe one of you has to test or similar use. However, I beg to using info, so that's what I what to see and look forward to. I myself will unfortunately not provide programmed, too little time and probably too stupid. Sorry for my bad english, I'm an untalented in foreign languages ​​German. See you later.

Wow those sprites are amazing. I would like to note that you are not too stupid to program a game. I think you could do it. Anyways I would team up with you if that is what you are asking. One who draws that good could make an awesome sega genesis game paired with good programming which I could do.

hello

thank you like the pictures. I have appended a few examples, a ship sprite animation, level building blocks and a constructional example with 4 32x32 pixel blocks. If I have time again follow more pictures.


ship animation 10 colors



screensho 1st layer bg 9 colors

hello

A few new pictures. A test for compression of large sprites of 96x56 pixels to 64x56 pixels shown. The background of the screenshot in the first post. Border for the second picture is yet another screenshot with a different second background layer. On the topic to make a game "sega16" I imagine very difficult before, but a demo level might realize. Convenient for me would be understandable routines to test animations of my sprites and so on for me. Personally, I never got that down, unfortunately. See you later.

Even though you save a couple of ( "empty" ) tiles using a layout like that .. it increases the number of sprites you need to use significantly ( 11* sprites instead of 6 ).



*And i even moved the tile below the top-left to the empty spot

The Genesis / MegaDrive can only display 80 sprites at once, so keeping the sprite count as low as possible is much more important than preserving VRAM / tiles.

You are definitely talented with creating graphics! Keep up the fantastic work!

hello

Another example for a smaller sprite and equal to a question. Is it better the upper sprites (4 sprites per 24x24pixel) displayed, or the lower (1st sprite 24x16pixel, sprite 2 and 3 per 24x24pixel, sprite 4 as 2 sprites, 24x16 and 8x8pixel).

The top sprites are the correct approach. The first sprite in the bottom row requires 2 sprites instead of 1 ( while only saving 3 tiles ), and the 4th sprite is invalid since you can't flip diagonally Always go for the least amount of required sprites.

Hi

Thank you Moon for this information. Direct a new question. In relation to a horizontal shooter, I have read here in the forum of something "rows and colums" called her here. Moon has posted in a post animated pictures of it. However, I do not understand the principle, as I use this on drawing the background. What sizes are suitable etc.

see you later

The MegaDrive has background layers of "only" 512x512 pixels ( by default ). So when you want to use maps bigger than that, you need to update the backgrounds while scrolling. Besides that it's rather slow to draw entire maps at once, so the trick is to only draw what is needed / has just scrolled into view.

For any horizontal-only scrolling game i recommend using a height of 256 pixels for your maps ( even though only 224 pixels will be visible ). Because 256 is a power-of-two number it makes things a lot simpler & faster. As far as "meta-tiles" / blocks are concerned, 2x2 tiles ( 16x16 pixels ) is quite popular, but 4x4 tiles is just fine too ( as seen in your mockups ).

In fact, here's a quick example using 4x4 blocks ( using a super rough interpretation of your map )

disable screen

loadtiles tiles,5,257
palettes palette,0,0,4

scroll up,16

reload map

for x=0 to 10
for y=0 to 7
read b
drawtiles blocks,256,x<<2,y<<2,4,4,b<<4
next
next

enable screen

do
time++

if time > 2304 then time = 2304

progress = time>>1
scroll2 left, progress

x = progress>>5
y = progress>>2 AND 7

reload map_scroll, progress>>2
read b
drawtiles blocks,256,x<<2+44,y<<2,4,4,b<<4

hello

Thank you "Moon" for the example. I can really understand it until now not yet but maybe still is. I would want to at least understand how I create with Imagenesis and SGTD tilesets can then be displayed correctly. I take some small sprites is the presentation correctly, but I let my big sprites with SGTD divide always comes only graphic garbage out there. I'm doing something wrong.


see you later

ImaGenesis isn't very convenient for big sprites. What i generally do when using ImaGenesis is split up sprites that are taller than 4 tiles and put them next to each other. And in case you end up with sprites that are less tall than the image height you're using, i recommend putting a easily recognizable pattern in those tiles, so you know which ones to delete.

Alternatively you can use multiple images and put the palette in the top left of the images, so they all use the same palette.



Anyway, here's your enemy ship in BEX

Hi

Thank you for the brilliant example of "Moon". Have included in BEX and loaded with the Everdrive your code. Very awesome that I can see even large sprites. As a result I will have to annoy you with questions about your code. A few things I already understood but certain things are a mystery to me, the Bex Help file can not help myself.

Sure, no problem. That's what the forum is for

hello

In the appendix to another level setting, additionally a screenshot with a larger opponent. Such images are always my first tests in grayscale. So the best I can reduce my scanned pencil sketches, rotate and so on. With Colored image templates that are considerably worse off, because the colors blur at a rotation by 15 degrees and any contour vanishes.

Now another question for "Moon" to his example. What tile size you stells a at exactly the image in SGTD? Are the color palette data that you have previously created with Imagenesis? If so knows where imagenesis the colors for the palette are in the top left image?


see you
