I just tried a space invaders attempt based on the tutorial but i cut out some of it like some of the animations to keep it basic.

1 problem i found was the more aliens i kill, the faster they move,
I've only done one level and havn't included anything to increase their speed.

Some how its going faster because of less code to go through, is there a way to keep the movement constant?

also there seems to be a buffer overrun when i close the program, dunno whats causing it.

I've attached a rar'd up version of my game

The increase in speed is probably due to the system having one less sprite to track and draw if you're deleting the sprite. To keep things constant you almost have to adjust the movement using floating point positioning based on the number of ticks that pass.

I have a program that uses up to 180 sprites on the screen some of which are hidden much of the time. No movement. When I added them there was a significant drop in my frame rate.

i'll try hiding them instead of deleting them after they've been hit.

Also on this buffer overflow after i have when i close the program, i had alook around but couldn't find much on it.
Most tutorials and help files just mention strings causing the problem but i don't use any apart for the dbLoadImage (image filename).
Also it was there before i used a string to put up the score at the end of the program.

What else could be causing buffer overflows?

thanks for any help.

if the speed is a change in FPS, you could try my technique which keeps games running at the right speed on even the worst PCs, instead of having set speeds, move an object by a speed divided by the fps. so the higher the fps, the less they travel per frame.

And you can use my ESP technique for determining what that method is. Oh, that's right. I don't have ESP.

Care to elucidate. I'm sure you posted it somewhere but without ESP I can't determine where.

I believe that is the method. Divide your speed by the FPS.

got the speed timing correct now, used to timers and looped program until every 100milisec, then it would dbSync() etc.

I'm still concerned about this buffer overflow when i end program debuggin. Havn't got a clue whats causing it.

also i've tried using the font.png to display the score at the end. havn't got a clue how it works, just some parts i know.
Anyway i tried dbText(...) and nothing shows up on the screen, i was wondering how to get normal text appear on the screen i.e. "GAME OVER!!" in the middle of the screen.

thanks for the help as always

how do you run the game outside of visual studio debugging?

I've got a .exe in the debug folder but when i try running that a window with a black screen comes up.

Look for similar threads. Most likely your media isn't where the program expects to find it.

Also, try generating a Release version.

Change the drop down on the toolbar from "Debug" to "Release".

got it to work now, copied all the image files used for the program into the same release folder to go with the .exe and it all works now.

thanks again.
