yeah....collisions are confusing, cause I don't think you can just put pxl-test(x,y+8) and be done with it.

fixed all my ram clear calc crash issues ( atleast that I know of ) And I have implemented gravity for realism!

here is an example:

[FFFFFFFFFFFF]->pic1
line(0,63,95,63)    //line at bottom of the screen
45->X
55->Y
-5->V      //velocity, change to adjust height
repeat getkey(15)
if getkey(4) or (pxl-test(X,Y+8)=0  //pressed up or nothing is below you
Y+V->V    //Keep in mind V is a negative, so it is like subtracting from Y, until it gets to zero....
V++      //This will get V to 0 so Y is added to
end
if pxl-test(X,Y+8)=1    //If you hit a line
-5->V   //resets your velocity so you can jump again.
end
pt-change(X,Y,pic1)
pause 50
displaygraph
pt-change(X,Y,pic1)
end


this gives the jump an arch

Oh, I know how to do that. I was trying to do pixel testing when the player goes very fast, so it doesn't go right through the lines. But I think I'll probably be fine since it won't be moving at like supersonic

lol I just did that with butts' velocity tutorial
(and it works too )

lol oh yeah sorry...question.....256 inflation maybe? I just realized its going through the lines

did you get it to work? could copy and paste it into my code example above, so I can see it?

Oh no I get the gravity, It's just he jumps through lines except the the starting line
