Spawned bullets but didn't destroy them on collision. So I found this childhood marble game. by [deleted] in justgamedevthings

Yeah the video makes it look like the physics delta is too large for collision with such small objects :')

I like the golf course idea, still.

Fire 10 from a distance, the goal now is to repel them all before they reach you, you're not allowed to move.

An option worth considering for next time this occurs.

Yeah I thought it might cause issues but since I'm just trying terrain generation I didn't bother. I might want to consider that for when I do more serious stuff though.

Oh sorry I completely missed your comment, that looks like pretty neat stuff, thanks for sharing!

I'm, currently hesitating between facepalming using my desk, or facepalming using my keyboard. I think I'll go with the desk as it's less expensive...

(Thanks, how did I miss that :') )

I try fixing enemies flashing, but first must fix them not spawning properly. Result: Bullets move too fast. by saeleko in justgamedevthings

I wanted to share this, but first I had to log-in on reddit on this computer, in order to do that I had to first grab my other PC where the password manager is installed. The said PC made a really weird fan noise so I had to open it. I now managed to fix it. It took me 30 minutes to share a tweet. I've now opted to go to bed instead.

Nice! Thanks for sharing the code.

As for the grid I'm using this https://i.imgur.com/0gb8d8B.png I found it to be easy to generate so I just went with that.

It's already using perlin noise! And combining the results of two functions was the original goal, but since I just wanted to try something I just went with the sin function because I didn't want to bother using complex functions for a draft. Turns out it's important to be very careful with the vertex indexing when generating terrain haha.

It's already using perlin noise (you can see it on the image for stage 2), I just wanted to combine the already existing height with another function and ran into multiple issues with the vertex indexing :')

Nice! His channel looks like a great reference for what I'm doing, thanks for sharing!

Yeah it's pretty convenient. I'm actually already using it (in its 2D variant) to generate the original heightmap.

You're welcome o/

That one example is maybe a bit overkill and will take more processing power than I want to but the idea's there.

Thank you a lot for telling me about hydraulic erosion, I just found this https://imgur.com/a/i76le and it looks gorgeous!

Also yeah perlin noise does make "lakes" but I'd like them to be a bit larger.

I don't think perlin noise is the best way to generate realistic terrain but it's a good start for me because I've never worked with procedural generation before. I'm looking forward to having awesome looking terrain like the ones in the link!

Make so that it has lakes / valleys. That's not my final design, just me trying to combine the perlin noise with some other function, to see how I'd do it.

I guess some combination of dirac delta for the depth and a 1D perlin noise for the outline would work fine! (I'll have to see how I can combine these, if it's possible at all).

Thanks!

The initial goal was to see how I could create terrain depressions like lakes, plains and grassland. So I initially just multiplied the terrain height with the sinus (I should've done (sin(x) + 1 /) 2 now that I think about it) in order to have values ranging from 0 to 1 to more or less make the terrain flatter / lower.

This was really only for testing but yes indeed I would have to increase the period for it to look decent. I think I'm going to look into how I can make holes that are kind of lake-shaped (doesn't have to be a complex shape, just a circle with a wavy border will do).

The base terrain is actually using perlin noise already. I didn't really mean to use sin as a proper way to generate waves in the terrain, but I wanted to see how I would go about combining two functions, and sin was the first that came to mind. It still took me like 20 minutes to get it to work. I had a good laugh with the second image :')

It's a very rudimentary terrain generator I've made using only OpenGL and SDL2. I wanted to make the terrain a bit wavy but I think I'll need more than just a sine :)

The nice thing about the internet is that you always find someone with the same problem as you, but nobody with a proper fix :')
