Space firebird Mockup

[baggey]

So ive used no types. Would like to get bullets moving better maybe a need for velocity?
Ive tried a timer interupt type delay for firing bullets.

Heres the code

You'll need these two images as well

and the .ExE note exe dosent seem to work?

  Not too sure what you're trying to do with the the timing, but it'd be best to use a time past type of approach.   So interval between redraws has less impact.

   Runs here, although it does take a while.  Not a good idea to open in such and odd full screen exclusive mode.

   when attaching materials please ZIP them into a folder,  it's a lot easier on everyone

The reason why i want this screen size is im trying to write and create retro stuff i dont want to be scalling and rezizing! yada yada! using clever fx stuff etc.

Why is the default size 800 x600? Why cant this be 320 x 240 / 256 x 192 etc? If we chosse to?

  Nobody has CRT monitors anymore, so LCD displays will scale it.

You set the default to whatever you want, but it's a lottery as to what hardware supports what.
