Runer, I wish I got anything of what you're doing there. I would like to try it anyway, where should I place it, before or after displaying the sprite?

You would want to have this code execute when your sprite is not currently on screen, so before you draw it. Note that if a collision is detected, this routine would jump to a Lbl COL, so you would need to add this as your collision handler.

I have a new question. How to order things in the loop so that everything works fine?

Code: [Select]
Repeat getKey(15)
...
End

I need to draw the tunnel, draw the sprite, check for collision and shift the screen

Here's the code to draw the sprite:

Code: [Select]
Pt-On(X,Y,Pic1
DispGraph
Pt-Change(X,Y,Pic1

I'm doing this:

Code: [Select]
DRAW TUNNEL
Pt-On(X,Y,Pic1
DispGraph
Pt-Change(X,Y,Pic1
COLLISION
SHIFT SCREEN
Shift Screen = Horizontal - (3 times)

However, it's not working. How should I make it?

I also tried:

Code: [Select]
DRAW TUNNEL
COLLISIONS
SHIFT SCREEN
Pt-On(X,Y,Pic1
DispGraph
Pt-Change(X,Y,Pic1
My problem is handling collisions because of shifting the screen (for example, X collision checking doesn't work because I shift the screen).

So, what order do you recommend?

First, you should try to use only one of Pt-On, Pt-Change, or Pt-Off if possible, as each is a couple hundred bytes in size.
Second, try:
Code: [Select]
DRAW TUNNEL
COLLISIONS
Pt-Change(X,Y,Pic1
DispGraph
Pt-Change(X,Y,Pic1
SHIFT SCREEN

The problem with your previous code was that you needed to close the parentheses of each pxl-Test. In your code, you were performing the or on the second argument of the pxl-Test, not the result of the pxl-Test.

In Axe it's always a good idea to close your parentheses and braces. Leaving them off doesn't save any bytes from the compiled version, and code can become more messy and harder to understand and optimize.

If you're used to the way it is in BASIC, just make sure you close them before an operation that deals with something other than the immediate value.

:crazy: I actually knew it didn't save any bytes in the compiled version, but didn't know it could affect my code. I'll change it and thanks, thanks thanks so much!

Why doesn't Text(x,y,"(text)") work?

If that's your exact code, the coordinates are a problem. The lowercase x and y mean nothing to Axe and will generate errors.

If, however, you just forgot to capitalize them in this post, I don't know what the problem is. Can you elaborate on "doesn't work"?

It may also be that he's calling a DispGraph routine and hasn't called Fix 5 yet, which would make it appear to not work.

Which Text command are you using?  Remember, there are two of them.

good point, Happybob ;)

Use the one with the parenthesis right after the Text (it looks like Text( in the catalog, not Text with a space)
