Has anyone had the idea of making a bullet hell shoot em up for openbor

Hey guys I know it's going to be a difficult question to ask, but the reason I made this thread because I wanted to see if anyone got any tips or pointers to make a bullet hell style shoot em up for the openbor engine. I don't why it suddenly came to my mind but it was out mere curiosity.

If I do plan on making it someday in the future, it should look like this:


Or this game:

It's not much different than doing a beat em up, code wise.

I see what you mean O'Illusionista, I just wanted to see how to make one because I saw someone made a shoot em up for the openbor engine (forgot the name of it). And since I'm a huge fan of bullet hell shoot em ups created by CAVE, I think that this is a perfect opportunity to make one in the future.
 
Making shmup with OpenBoR isn't hard. There are 2 ways to do it:
1. Using x z plane aka default plane
This is also used to make road fight or something like that. This way is easier since no extra coding is needed to create the basic. You can use default knife shooting mechanic for this
The downside is using this to fake #2 below is: positioning can be confusing since z axis works the opposite of y axis. And gravity can't be used in z axis
2. Using x y plane
This way is harder since scripts is need to create the basic. You also need to script shooting mechanic since knife shooting can't be used to shoot downwards
The bright side of using this is : positioning is easy and gravity can be used

I was imagining shmups where players are on left side with background autoscrolling to the left when I typed the above

For shmups where players are at the bottom with background autoscrolling to the bottom, it's also doable. and judging from the nature, #1 above can be used.
 
I think I understand now, thanks for showing me the basics of how to make a shoot em up Bloodbane. I will use this to make bullet hell style games for the openbor engine very soon. 😊
 
I would go with the X Z plane - its what I did on my game.
You just need to take care with the attackbox and bbox Z size (yes, bbox has a Z width too), you would need to me very aligned with the target

Thanks O'Illusionista, You guys are very helpful with showing me these examples to make a shoot em up. Now I just have to find the sprites and backgrounds to make a sample gameplay, I think i'll check both Spriters Resource and Sprite Database to see if any game has them.
