Portal Gun in Sonic 2

xposting makes you cool

​

about

Hi guys, long time no see. Time for another mini project.

The portals in the game actually affect objects other than sonic - to the extent that you can kill an enemy with its own projectile if you fling it back at it.

I attempted to recreate the portal gun as best I could, but it turns out the sonic engine isn't a huge fan of warping. You can probably break the game in many unimaginable ways, but I think I covered all the major issues.

I am posting this now as I'd like to focus on another project. However, I would happy to donate the source if the community took this and made an actual puzzle based game with custom levels using these mechanics.

Many thanks to E-122-Psi who agreed to build this fantastic spritesheet.

I saw this on Retro, but wasn't able to respond there. I'm very happy to see both that portals legacy hasn't been forgetton (for love of god, valve, make portal 3)! This hack is very enjoyable and very fun to break (you can absolutely ruin the silver sonic battle with portals XD). Also, if you go through a portal whilest dying, you can come back to life, granting invincibility as long as your close to a wall or floor.

 

Everyone knows Valve forgot how to count to 3.

Anyhow, this is great! I really love the concept and it's really great to play around with.

(Also, sorry about my sprites not working out. I feel like I wasted your time with that.)

 

They used to say the same about Capcom and they're already up to Street Fighter 4... 's rereleased version Ultra Street Fighter 4.

 

At least they rereleased the games to show the series was still alive. I haven't seen any thing like that for portal or half life (imagine if they made Portal 1 with the improved engine and models of Portal 2! That would be heavenly!!!)

 

Wow, never expected to see you back around here, how's life?


I'll be sure to give this a try when I get time, I'm a big fan of the Portal games.

 

Haha, glad to see you're still around.

All's good, I live in salford now. Starting to get back into stuff

 

Interesting hack. I tried it through CPZ1 & got stuck in a wall for a while. I had to work the portals out to free Sonic. Tried it in DEZ  & at least i found a strategy to have RoboSonic, but skipping him seems a no-go.

Now we can say Mario ain't the only one with a Portal Gun

 

This is a very cool hack. But I had one problem when playing - Sonic dies in cutscene after beating WFZ boss. The only way to beat the game in one go is to place portals in WFZ with pixel perfect accuracy.

Ah still around Manchester then. I actually work near Salford in Trafford Park. What got you back into it all then?

Decided to pick up work on Boom again The Portal Gun hack is a side project while I work on that.

 

That Super Sonic spriteset is very awesome :good:

 

I found an odd bug. When you go to the continue screen, it will show tails, but with some garbled looking graphics. Continueing will result in the portals show tails' graphics from the continue screen, which looks really weird.

 

Oh hai guys, I'm here and now I'm here and here and ther- This hack is so awesome.

 

Truly awesome hack. I'm actually a fan of Portal games, and that was a great thingy to play. Once I got stuck because game didn't change planes or paths (loops, etc.), but anyway, it was fun

 

I know it's a huge bump, but it's contest week, and this hack is in the contest, so it makes sense to post my "Let's Try" video in here!
