You'd better make the sprite a little smaller.

This looks nice guys

In the real game, the enemies are 1.5 times bigger than mine, so it might be easily playable

could be, but your screen is about 8 times smaller

it really is too big i think, since the field is only like 3 guys high...

but ok, if you don't want to change it, it stays an extremely nice game

Sorry, but the field is like 5 guys high : my chara is high of only 12 pxls

EDIT : I saw a problem in your sprite, saintrunner : still my screen is little, the ground where the chara runs might be at the real bottom of the screen, can you change it ? Else I'll use it as it is.

EDIT 2 : I finished convert all in hexa (saintrunner, I'll hate you for that

), and here is the result :

As you can see, that's awesome !

EDIT 3 : I paste the ground and the bottom of the screen :

I think I can fill the blank on the top of the screen by inserting 25% gray between the bottom and the top of the image.

You really should make your guy smaller.

I have some scrolling issues : I want to scroll my pic but I don't really know how to do that. The bitmap() functions is really too slow, and I think of use Horizontal -(BUF) then Copy(BUF), but I don't know how to reblit the same pic at the right of the first (to scroll).

Right now, I have this :

Code: [Select]

:prgmJTPKBG
:Buff(768)->A
:Buff(768)->B
:Copy(Pic1BG,A
:Copy(Pic1BKG,B
:
:Repeat getkey(15)
:Horizontal -(A
:Horizontal -(B
:
:Copy(A
:Copy(B,L3
:DispGraphrr
:End

It works, but only scrolls the pic once. How can I blit the second pic at the right of this ?

You're trying to make a pixelmapping, good luck on that.

PS : you don't need thoses buffers.

Matrefeytontias · « **Reply #23 on:** March 25, 2012, 07:11:41 am »

Actually that's ok, I found 2 hours ago

Yes, I need these buffers because I clear both buffers each cycle, so I use them to keep the pic displayed somewhere (in order to apply Horizontal - on it)

EDIT : Here is what I reach :

That's not really pixelmapping, though

kindermoumoute · « **Reply #24 on:** March 25, 2012, 01:16:28 pm »

So if you use a 1536 bytes buffers, please use it outside the game. Eg. in an appvar that can be deleted at the end of the program.

Matrefeytontias · « **Reply #25 on:** March 25, 2012, 01:20:38 pm »

Yeah, but I just saw something : in game, it's slooooooooow

Now, I have this (bit checking) :

Code: [Select]

:.X2t is the buffer 1, Y2t the buffer 2
:.There are 8 empty pixels at the top of the image
:
:DS<(C,2)
:For(r1,7,63)
: {r1*12+X2t}e0→{r1+L2
: {r1*12+Y2t}e0→{r1+L2+64
:End
:
:Horizontal -(X2t
:Horizontal -(Y2t
:
:For(r1,7,63
: {r1+L2} or {r1*12+11+X2t→r2}→{r2
: {r1+L2+64} or {r1*12+11+Y2t→r2}→{r2
:End
:End
:
:Copy(X2t
:Copy(Y2t,L3

That leave the game at an normal speed, but now that's the background which is too slow

how can I have fast speed and fast scrolling ?

I'm not exactly sure how you're doing it, but the way I'm doing the scrolling backgrounds in Essence is I horizontal +/- the buffer, then look through a stored image and copy a column to the screen.
However in your case you might be able to get away with not having a stored copy because it's the same size as the screen.

I'm assuming you can only scroll to the left...
Maybe try this: First check the part of the buffer that's about to be scrolled off the screen.
So if it's scrolling leftthen you'd check the leftmost bit in each row ( {[row#]*12}e0 ), and store the results somewhere.
Horizontal - as needed
Then go back through the bits you checked earlier and effectively copy the column that was scrolled off the screen (on the left) to the other side of the screen (the right), giving the impression of scrolling

( this should be possible by working down what you stored earlier and doing pxl-on to the buffer)

He wants probably update screen to display rockets and jetpack every loop.

Darl181 · « **Reply #28 on:** March 25, 2012, 04:12:50 pm »

Then he'll probably a stored copy...which he could modify on-the-fly to scroll.
Maybe when he goes to Clrdraw, he could just copy the background to the screen because that writes over whatever's on the buffer in the process

That looks awesome. I'm curious how this will look like
