SetVirtualResolution(768,1024)
//UswNewDefaultFonts(1)

playerx as float
playery as float
//lazerx as loat = -100
//lazery as float
//enemyx as float
//enemyy as float
//enemy_direction = 4
//score=0
//stars as integer[50,2]


#include "Loader.agc"
#include "PlayerMove.agc"
//#include "Player shoots.agc"

Gosub loader()
//gosub make_stars
//gosub load_sounds
//gosub load_music

do
Gosub Playermove
//
//
//
//
//
//
sync()
loop

(loader):

loader:
LoadImage(1,"Player_ship.jpg")
//loadimage
//loadimage

CreateSprite(1,1)
playerx=GetVirtualWidth()/2 - GetSpriteWidth(1)/2
playery=GetVirtualHeight()-GetSpriteHeight(1)

SetSpritePosition(1,playerx,playery)

return


(PlayerMove):

Playermove:

playerx=playerx+GetDirectionX()*12
playerx=getpointerx()

if playerx<0
playerx=0
endif

if playerx>GetVirtualHeight()-GetSpriteWidth(1)
playery=GetVirtualWidth()-GetSpriteWidth(1)
endif

SetSpritePosition(1,playerx,playery)

I just edited your post because you didn't use code tags. code tags make the code much more readable
and they are compulsory. A code tag is used by clicking the Code button at the beginning of your code
and at the end of your code snippet.

the lines

+ Code Snippet

#include "Loader.agc"
#include "PlayerMove.agc"

may be where the problem is in one of the included agc text files

well spotted !! (that very well might be the problem)

personally i prefer to not use gosubs at all and go for functions

Here's my two cents. I think when fubark edited the post, he didn't realize that the "()" bracketed parts were meant to show that it was a separate agc file.

As for his problem, it's his first Gosub command that is failing. He's attempting to jump to "loader()", when none exist. It should be changed to "loader"

The brackets arent the problem... it still wouldn't work...
and as you probably already noticed, im completly new to this program

... but i have read so often, that the most people use funtcions rather than gosub.
I only have no idea how these works. Maybe someone can rewrite my program with functions.

This post has been marked by the post author as the answer.

code below compiles ok , temporarily commented out the includes as I don't have those.

+ Code Snippet

SetVirtualResolution(768,1024)
//UswNewDefaultFonts(1)
 
playerx as float
playery as float
//lazerx as loat = -100
//lazery as float
//enemyx as float
//enemyy as float
//enemy_direction = 4
//score=0
//stars as integer[50,2]
 
 
`#include "Loader.agc"
`#include "PlayerMove.agc"
//#include "Player shoots.agc"
 
Gosub loader /*()*/
//gosub make_stars
//gosub load_sounds
//gosub load_music
 
do
Gosub Playermove
//

Brackets were the problem

I copied the code from@ Bored of the Rings and it compile 100%

Did you remove the character before #include "loader.agc"?

+ Code Snippet

`#include "Loader.agc"
`#include "PlayerMove.agc"
//#include "Player shoots.agc"

If so, then it can't find the loader.agc file.
Make sure "loader.agc" it is in the project folder

I would also suggest buying one of the Tutorial Guides
"AppGameKit Official Beginners Guide" is very good, and do a bunch of examples, that will give you the basic understanding...

The Forum also have a lot of examples... sometimes a pain to find them with the search, but they are there...
