Problem Moving Screens

[dabyx]

Hi everyone,

It's me again.

I seem to be having a slight problem when using SCREENLEFT/RIGHT/UP/DOWN

On certain screens I get sprites appear where they shouldn't

In this video at the top left, the player sprite appears on screen2 but every other time.

Screen Issue

I also have some screens place multiple player sprites and other unknown graphics when moving between them.

I have tried adding a REDRAW, a CLS and REDRAW (and RESTART but that positions the player incorrectly)

and nothing seems to work.

Does anyone have an idea what is happening and why?

Many thanks.

Look inside that sprite positions screen, and see if there's an extra sprite there.

That's not it. In the above example, the sprite grpahic is out of the game window. (Also just double checked positions)

Another example is going from

This Screen

then SCREENUP to

This Screen

A lot of garbage sprites here. Which CLS and REDRAW do not remove.

Hello, this happens because you have not defined a player position on those screens, place a player position on those screens and you will see how garbage no longer appears.

Oh! I didn't realise it was a requirement.
I'll give that a go, thank you. 🙂

So if I wanted to have the player in different locations depending on screen entry I would also have to add extra code I'm assuming?

Edit:

Oh the program knows when the player has entered the side of a screen no matter where the sprite position has been placed.

That's great!

Thanks everyone for your help.
