Beginners > [Solved] sprite arrival problem [WIP] My first game

#21790 - Sanktuaire - Sat Jun 05, 2004 6:43 pm

Firstly please excuse my poor english (i'm a french newbie developper).
I 'm learning programming games on GBA and I have a problem with the arrival of my sprites (enemies) on the top of the screen.

Here is an exemple of my problem :

tyrian.gba

Version online

the enemie doesn't arrive but appears :/ because the y position is initialized to zero.
I tested with modulos but that did not solve my problem and when y gets a negative value, sprites are all messed.

It would be great if anybody could help.

Thanks.

The problem is a sprite doesn't work right when it has a negative value it's value should be from 0-255. Was this your problem that you solved?

Also that's a really interesting game, nice work. Please let us know if you finish it.

Wow, I loved Tyrian back in the old days of DOS! I think that's awesome that you're doing a remake of it. Good job so far :)
