Hello Programmers,

I was wondering if anybody could give a descriptive tutorial on how to make a shooting game. I cannot seem to figure out how to make rapid bullet fire and how to make multiple ships move around the screen. Thank You very much for your time and cooperation
 

If you know how to handle one object, it is easy to handle several, using a For loop.
For example, to move one pixel from left to right, you do that:
:0->A
:While 1
:  Pxl-On(A,0)
:  DispGraph
:End
(yeah, infinite loop, I don't care)
...

I'd go for this:
:0->A
:While 1
:  Pxl-On(A,0)
:  A+1->A
:  DispGraph
:End

And if you use repeat getKey(15) instaed of While 1, you can quit the loop by pressing clear. But Hayleia has already said the most basic thing: If you know how to do one thing, you can easily do it multiple times by putting it in a for loop.

Lol at first I had a A++ in the EndIf, which also means that my loop was not infinite, but then I wanted to simplify and forgot to put the A++ back -.-
And While 1 / EndIf getKey(15) is more optimized than Repeat getKey(15) / End

(fixed my previous post)

Well, as everyone in this thread said before me (), if you can move one bullet, you can move 100 of them with a For loop. This is where arrays are useful.

The things you call "arrays" don't really exist in Axe, since there aren't any data type nor anything. What's there is plain RAM. But you can easily use it as an array-ish variable.

For example, let's use L₁ ([2nd][1]). It's a pointer on a 768 bytes free RAM area, so it should be enough. Although it's in fact a simple area that you can go through using {r₁+L₁} where r₁ goes from 0 to 767, you can also use another technique : use {r₂*X+r₁+L₁}, where r₂ goes from 0 to the number of rows minus 1 of your "array", X is the number of colons in your array and r₁ goes from 0 to X - 1. Thus, you can pass r₁ as the colon of an element of your array, and r₂ as the row. And poof, you have an array.

1.No, you have to make your menus by yourself and it is not that bad. And the Z-Test command is quite useful for that if you want something that looks like Menu(.
2.Strings are, like any kind of data, handled by pointers, so just add an offset to your pointer. For example, if Text(0,,Str1) displays "wattouat", then Text(0,,Str1+1) displays "attouat" and Text(0,,Str1+2) displays "ttouat".
3.I didn't understand anything to the question

hey everyone
i´made a pic format for my own progs...
it is stored and executed in basic...
now i´m trying to port it into axe,but the axe prog is ram clearing...
info :
picsprite is stored into str1

prog for executing in basic:

:"?º'{^r}!{^T}{dot}{cross}{box},/*-+π{E}{e}{^3}{^2}{^-1}{}():."→Str0
:For(A,1,length(Str1)
:sub(Str1,A,1)→Str2
:inString(Str0,Str2)→B
:A+1→A
:sub(Str1,A,1)→Str2
:inString(Str0,Str2)→C
:Pxl-On(X+B,Y+C)
:Endin axe:
:.ASCLPIC
:GetCalc("Str1")→A
:GetCalc("uX")→{X}{^r}
:GetCalc("uY")→{Y}{^r}
:"?º'{^r}!{^T}{dot}{cross}{box},/*-+π{E}{e}{^3}{^2}{^-1}{}():."→Str0
:""→Str4
:length(A)=L
:conj(A,Str4,L)
:For(B,1,length(Str4
:Str4+B→P
:For(C,1,length(Str0)
:If Str0+C=P
:C→Z
:B++
:Str4+B→P
:For(C,1,length(Str0)
:If Str0+C=P
:C→θ
:sub(DW)
:End
:End
:End
:End
:End
:
:Lbl DW
:Pxl-On({X}{^r}+Z,{Y}{^r}+θi hope i find some help here...

well i use them because i ´want to make this tool for basic programmers
x and y are pointing the sprite on that part where the basic prog it defines
and str1 is the sprite itself...


Buff(2)->°X
Buff(2)->°Y
is not working

axe parser shows
:err:name length 

i changed getcalc( like jacobly said and it is every time showing a pxl at 10/60

the ehole prog is not working !!!!!!!!!
i need some help
is there mabey anywhere sth wrong...
or mabey you have another  possibility....
