Life Force for the HP Prime
« on: January 14, 2014, 03:20:46 pm »
Anyone here ever heard of Life Force (part of the Gradius, Salamander and Gradius family of shmups)? I am considering making a shmup based on this game. So far I have scrolling background done. We will see if the HP Prime can handle games with complexity on the order of NES games.

I don't think I heard about it, but I know Gradius and such shooters. It would be interesting to see how the Prime can handle them. Hopefully the scrolling background won't slow the game down too much (although my concern is more if the game is Touhou/IkarugaX-like and there are too many bullets on the screen).

It's not really a bullet hell. There are enough bullets to make your life miserable at times though.
If you like my work: why not give me an internet?

Sounds awesome Han! It'll be interesting indeed to see how well the Prime handles this sort of game. :D

I attempted a similar project once, based on Nemesis (Gradius rebranding) for the MSX1. I actually still have the assets if you want to use them. The project has been dead for years, so feel free to use any of the materials for any purpose.

An advance warning: My project files are extremely disorganized. I threw all the sprites into a rather sloppy PNG file. The level maps and tileset are in CalcGS format, so I included the program's executable in the ZIP file as well.

Oh I remember that and it looked pretty good. I wonder how this could be adapted for the 320x240 screen. Of course, nothing stops anyone from using a smaller resolution, though, since the images on the HP Prime can be scaled up/down.

Zera,

Thank you for sharing! I'll hold off on peeking too much into your code for now. So far I have only looked at the sprites. I would like to see if I can get this project off the ground from scratch. Your mockup certainly looks cool, though!

Can't wait! (It'll be interesting to see how you'll handle the bullet sprites.)

Here's a sneak peak of the current progress!

Can't wait! (It'll be interesting to see how you'll handle the bullet sprites.)

I have come up with several techniques; the real question will be which one is the fastest. I will probably put a soft limit on the total number of movable objects on the screen and see how the machine handles everything. So far, I'm pretty impressed with what this machine can do. The current main loop even requires a delay in between frames in order to slow it down since no delays means the scrolling goes by too fast (even if it's single pixel scrolling). We'll see what happens when more stuff is added.

Woah this looks absolutely cool Han! O.O I would like to see a screenshot, though, since on video it's kinda blurry.

No, those are bg tiles and signify "walls."

Below is a screen shot from the emulator.
