...inflation by 256 makes the jump a lot slower but by changing some constants you can get a pretty fast jump "even" with inflation by 256.

Cool... I'll have to look more into that later. In the program, the jump was rather slow, but if there is a way to make it go faster, its definitely something I'll look into. Thanks for showing me that.


Taking out the pxlText(X,Y+8) won't help. My character just falls through the screen if I place him on no platform. If I do place him on a platform, however, my character jumps infinitely as long as I hold the "2nd" button. I tried altering more of the code that had to do with jumping, but no luck. I think I'm getting somewhere though, so it shouldn't take too long before I can find a solution. But if it involves a completely new command, then I'll be stuck again.


Is it possible to render a line invisible but still in the game? If so, I could just make an invisible line, and make the code treat it as a platform that my character can jump on, but in-game the player won't see it.

Well, this might be very helpful.

Since I'm more comfortable with Axe, I'll decide to use when I'm more experienced with commands and sprite-making.

But this should prove useful for regular calc game makers. It's pretty nice! 

Thanks guys.

Taking from what you said shmibs, I actually did find a way to make jumping better. I simply took out the code "If Y<55, Y+1->Y", because the code I implemented was better.

If getKey(54) and (pxl-Test(X,Y+8))
15->J
End
If J>0
Y-1->Y
J-1->J
End
If (pxl-Test(X,Y+8)=0) and (J=0)
Y+1->Y
End

It was similar to the code that I saw earlier in the Axe forums, except that I needed to adjust within my code, which promptly made me remove the "Y<55" thing.


Hayleia, I sort of don't know much about inflation, so I don't really know if I can do the operation about making the positions different than 256 (unless I already did do it, but I didn't notice). I think I do understand what you're saying, however, about my character skipping a lot of pixels. When I made a 8x8 square on the screen, my character couldn't even stay on half of the square without falling through. I hope that that was what you meant. I guess I could just search through the forums again.


One question though: How could I change the code so that my character doesn't have to be on a line in order to jump? One part of my game deals with this (kinda).

I've been recently programming using Axe, and I have made myself a few programs that mostly involve small little picture animations. Not too long ago, I wanted to start my own side-scrolling platformer. I have been using previous topics and videos about making a line border and everything, and I made a simple moving engine. The only problem is jumping. I made what looked like a jump engine, but the problem is that its... static.

Maybe my code from the program source can give some insight:


.PLATFORM
...
X X value
Y y value
...
40-> X
5-> Y
ClrHome
[FF99BDFFFFBD99FF]-> Pic1
Repeat getKey (15)
ClrDraw
Pt-On (X, Y, Pic1)
Line (0,62,95,62)
Line (0,0,0,62)
DispGraph
If getKey (1)
Y+1-> Y
If Y> 54
54-> Y
End
End
If getKey (4)
Y-1-> Y
40-> Y
If Y <40
Y+1-> Y
End
End
If getKey (2)
X-1-> X
If X <0
1-> X
End
End
If getKey (3)
X+1-> X
End
If Y <54
Y+1-> Y
End
End
*The general layout is based on Scout greyscale tutorial and from an author of an AXE Parser video.

When I compile and run the program, the movement and the simple gravity engine work fine, but my jumping seems to be erratic. I was hoping for a fluid jump and the sprite going back down even if I held down the jump key, but instead, the sprite stays up as long as I hold the jump key and the sprite doesn't show its animation for going up to the bound of 40 that I gave to the Y var.

I've read other topics on the issues of jumping, but they don't seem to help me. An explanation with a fix/optimization code is what I need, because for now, I'm kinda stuck.         Any help would be appreciated.

Nice! I was waiting for revive to work. Works great now.
Great to see that the new shop is out now.
