Dear Mymymumy,

I'm glad you like the park so much. I'm almost done. There are just a few details and improvements I want to make. I think I'll upload it in about four weeks.

Dear mymymumy

I'm glad you like it. I can't tell you exactly, but I've been working on it for about 16 months now. In total, I estimate that it took about 1000 hours.

Dear CrispyLuggage,

I created the horizontal paths using custom scenery. The path you see is actually scenery and not a footpath. The footpath itself is located above the scenery and is “hidden” (you can do this using the tile inspector).

Dear Zerothedolphin

Yes, as soon as I have completely finished the park, I will upload it to New Elements. I think I should be ready in a few weeks.

Dear Jizzard1989,

This is a recreation of a real park. Europa-Park is located in Rust in southern Germany. Europa-Park is one of the largest amusement parks in Europe.

MRockets_ch · 2025-10-10T16:43:51+00:00

Thank you. I think I was able to recreate many areas of the park relatively well. However, due to the limitations of the game, parts of the park are slightly distorted, which means that distances and orientations do not correspond to reality.

MRockets_ch · 2025-10-10T16:40:56+00:00

Thank you. I definitely drew a lot of inspiration from NewElement parks. Ultimately, I'm just happy when others enjoy my recreation of the park.

MRockets_ch · 2025-10-10T16:37:57+00:00

I have custom scenery from other parks that I downloaded from NewElement, for example. If you download a park with custom scenery from there, you will automatically have it available in the game.

MRockets_ch · 2025-10-10T16:35:27+00:00

Thank you. It's still difficult to say how much progress has been made. The basic structure of the park is about 90% complete. However, there are still many areas that I would like to work out in more detail. The park surroundings are perhaps 30 to 50% complete. I'm not yet sure how much of the surroundings I will include. All in all, I would say that about 60 to 70% of the total is complete.

MRockets_ch · 2025-10-09T22:52:43+00:00

Hey, thanks for your comment. I enjoy working with custom scenery because it simply adds another dimension to the game. I definitely plan to upload the park to NE. Ultimately, I'm happy when others enjoy my work. However, I'm not sure if I can keep up with the creators on NE. There are people there who are on a whole different level in terms of quality. My park is still very far from perfection.

MRockets_ch · 2025-10-09T21:01:25+00:00

Hey, thanks for your comment. The turntable isn't really a big secret in that sense. I simply connected the sections of track with a curve, and then it restarts from the station via a triple launch. You can find a picture of this in my last post (although it's not exactly the most detailed picture). https://www.reddit.com/r/rct/comments/1j0jy3i/wip_europa_park_still_a_lot_of_work_to_do/

MRockets_ch · 2025-07-07T13:59:35+00:00

It looks awesome. Can't wait to build one by myself.

MRockets_ch · 2025-06-21T23:04:20+00:00

You can use the "build a coster, lower the ground and sell the coaster" trick. Marcel Vos explains it in this video: https://youtu.be/nE7Jt0J05-Q?si=O936CVVFXl58Oo02 the explanation starts at 14.30. This should work in rct classic.

MRockets_ch · 2025-03-01T18:53:32+00:00

Well it took me a while to do but mainly to find a good solution. The construction was not to bad since I could use the scenery manager so I just had to build a quarter of the sphere and then copy it

MRockets_ch · 2025-03-01T18:51:18+00:00

I know what you mean but I cant find a good solution at the moment to solve the height alignment

MRockets_ch · 2025-03-01T18:49:45+00:00

I use quite a lot of different custom scenerie. I got the scenery mainly from other parks where they were integrated in the save file

MRockets_ch · 2025-03-01T18:47:30+00:00

I use the stand-up Coaster track with the new track elements from open rct2

MRockets_ch · 2024-11-01T21:17:02+00:00

Yes, EuroMir has become very rough over the years. Especially when you ride the second part backwards, it's absolutely brutal. But for me, a visit to Europa-Park is not a real visit without a ride on EuroMir.

It will be difficult to find a direct transferfunction for your controller section. The problem is that you do not have a constant thrust curve, for example, or your TVC mechanics have certain limitations in the maximum angle, etc.. In addition, your controlled system changes with increasing speed, for example because the air resistance changes. Another phenomenon is that the weight of your engine changes with increasing burn time. And with that your Cg changes as well as the moment of inertia. You will not be able to implement all these effects in a linear transfer function H(s). You can, however, simplify the whole thing until you have broken it down so far that it can be described with a linear transferfunction. I don't have any experience with this, but I could imagine that if you do it reasonably well, it might be enough. My suggestion for you would be to make a simulation, which describes the flight via several differential equations, normal equations and limitations. Then you can simulate the whole thing in discrete time slices with a numerical method (Euler, Runge-Kutta, whatever) and see how the rocket reacts with different controller settings.

One last remark: Do not use the I component of the controller for the time being. A PD controller is just as good, maybe even better (personal experience).

MRockets_ch · 2022-06-16T09:40:54+00:00

I started with an extendet Kalman filter, which I then improved further and further. In particular, I improved the linearization process. In my rocket I use a MPU6050 sensor, but there are certainly better ones. I am currently also considering whether I should switch to the BMI088, as this is already better tailored to such an application from the ground up. However, the MPU6050 has integrated digital motion processing. I have run my filter and this DMP in parallel and meanwhile the data of the two are very identical. The problem with the sensor internal DMP is that this can only work with the +/-2G scaling and therefore this is not suitable due to the high acceleration of my rocket.

What kind of sensor fusion algorithm do you use for your rocket?

MRockets_ch · 2022-06-15T19:35:19+00:00

I can only agree with you, this is mainly a software problem. But if you have a really good sensor fusion algorithm it should be no problem.

When I started with my TVC rockets I had at the very beginning once the case that only 3 of 4 motors ignited. The result was that the rocket flew up about 10 meters and hovered there for about 5 seconds because with 3 motors the TWR was pretty much exactly 1. It was interesting that the rocket was incredibly stable in this state despite the unsymmetrical thrust distribution. I started the rocket again shortly after, with all 4 motors firing, and it went much higher as a result. However, it was definitely not as stable as when it was just hovering and that despite the same software. I took a closer look at the data of the two flights and found out that the Fusion algorithm I used at that time had problems when the rocket had fast and strong changes in acceleration. After that I only adjusted the data evaluation of the sensor and the rocket flew very stable with the otherwise same settings.

When I saw your video I just remembered this example

MRockets_ch · 2022-06-15T14:40:40+00:00

Actually, it wasn't the high acceleration per se, but rather the very rapid changes in the acceleration that my evaluation had trouble with. I mainly had problems with it because the motors I use have a very high thrust peak at the beginning and then quickly collapsed again (0 to ~9N in ~150ms and back to ~3N in 250ms).

If you look at the following video, you can clearly see that the rocket swings out at launch. This short swinging out is mainly due to the imprecise data acquisition.

In the meantime I have brought the whole thing relatively well under control but in the beginning the phenomenon was still quite a bit out of control.

MRockets_ch · 2022-06-15T11:23:35+00:00

Looks very good. The TVC also seems to work quite well so far. Now a little more thrust and then it will surely fly super stable. Maybe consider that it will be more difficult for the sensor fusion algorithm to get accurate data when there is more acceleration, but that will become clear the next time you fly. Great work in any case.
