Why can't the player move beyond his starting point?

[man2600]

hi guys!, i have been making a game in batari basic from scratch, and i was testing it but for some reason, it cant move beyond his starting point or does it return to it, im not sure but does anyone have any idea what it is and how i can fix it ?

 

 

im going to leave the code here:

 

default.bas

From a cursory glance, you are loading a value for the player's x and y positions in the main loop.  This will keep putting the object in the same spot.

 

player0x=27

 player0y=48

Yeah, you have to be careful where you declare the initial starting values for sprite locations as you could have some code to control the movement later and then in the kernel yoyo them back to the original starting spot before the drawscreen.   I've learned that lesson myself... repeatedly... over and over.

so that means i have to set the player0y=48:player0x=27 out of the go to main

If you want it just for initial placement, do it before the main declaration.

Yes, you can set the player's initial position in the "start" loop. Also you don't need to go to the "sprites" label as they are defined in the "main" loop. And bB sets the tv-type to NTSC by default so you also don't need that line.

Just have a look at this re-arrangaded version of your code, it works as intended:
