So yea, just finished Timo youtube guide.
Sorry Timo, when you asked me yesterday, If I learned anything from your video, and I said no. I thought you referring to your sample videos that you have of game snippets.
This guide taught me a lot. I’m going to repeat it again.
All I want do now for this code (which I don’t think is deep) should be beginner stuff for me is code to do the following:
* Slow down the scrolling speed.
* Prevent my pixel guy from flying. Just natural physics.
* Walk on the ground not through it and not through walls.
Can anybody hook me up with this code or guide me to somewhere that teaches me these specific things I am asking? Thanks.
This is the code:
GAMEPAD 1
BG 1
BG COPY 0,0,32,32 TO 0,0
X=64
Y=64
DO
BGX=BGX+1
SCROLL 1,BGX,0
IF UP(0) THEN Y=Y-1
IF DOWN(0) THEN Y=Y+1
IF LEFT(0) THEN X=X-1
IF RIGHT(0) THEN X=X+1
SPRITE 0,X,Y,TIMER/8 MOD 2 + 1
WAIT VBL

UP acts like a JUMP Button... would be better as A or B but wanted to do as few changes a possible....

@was8bit
this is awesome! thank you.
these bits of keywords will help me learn. i’m still breaking post your other code.
i’m at work, long day today and tomorrow, but expect me back this sunday.

Well, i forgot to tell you that the 2 important CHECK subs come from Timo's program..
https://lowresnx.inutilis.com/topic.php?id=318
And also my "gravity" is abit of a quick hack, there are a few different ways to do gravity and jumping, depending on how you want the playaction to feel ..
Sprites interacting with background cell charactes can be tricky when you allow free pixel level movement, which you almost have to do when jumping...
If your game is top down view with no jumping, (like pacman) you can use a movement trick that restricts movement to cell to cell only, so no fancy pixel checks, just check the cell your player wants to go to, and if it is empty then perform exactly 8 pixel movements on players sprite and presto it ends up in the empty cell perfectly :)
