Algodoo

In addition to those lights as I mentioned above, there are a couple of other things that will improve how your scene operates.

1. Remove the collision layers from the red light located near the end of the barrier arm because it interferes with the sign that reads "Awas Kai". You can also remove the collision layers from the sign if you want to because they serve no purpose.

2. In the axle that moves the barrier arm, check the checkboxes labled "Brake" and "Reversed". The "Motor" checkbox should not be checked. Also the "forward" direction should be controlled by the "up" key (do not check the "toggle" checkbox). The "reverse" direction should be controlled by the "down" key (do not check the "toggle" checkbox). To raise or lower the barrier arm, simply press and hold either the up key or down key until the arm is fully down or fully up.

After you make these changes, the RR crossing should work correctly.

No problem. Get some rest and then later decide if you want to improve this scene. I only make suggestions, but it's your decision if you want to spend any more time on it. You don't have to fix it if you don't want to.

Nice job on the scene's form and function!

Is this an example of a real world device and how it works (with air, of course)?

"oh no you gold on fire to save gold play". HUH?

Okay, here is a komment for ya (only 15 years later!)

42 -- I made it past the TOT, but where do I go from there? Is that all there is in this game?

Yes, many times!

I recall seeing this type of bearing that supported the X/Y table on a large industrial laser heat treating machine (circa 1980's) but I didn't know how they worked. Thanks!

Your English is as good or even better than many people who use Algobox!

Yes, I would be happy to assist you if you have questions in the future. Helping people is part of my job here on Algobox.

Okay, thanks. I'll try it again with your suggestion.

You're only in the 3rd grade? Wow, you are very smart for your age! I believe that you have a bright future ahead.

My suggestion is keep learning as much as you can about science and math, and then as an adult you will be very successful because smart people usually get high paying jobs.

alphinoxready -- Are you a pilot? Back in my younger days I flew mostly Cessna 172 Skyhawks. I also put some time in a Piper Cherokee, but most of my flight time was in Cessnas because those are the type of airplanes the flight school had.

When I first saw your scene, it didn't click in my brain that Aztec is a model of airplane made by Piper. But after I did a search then it made sense!

finns -- blade20 is correct. In a true spring engine, the power to move the piston comes from an unstable spring. In your engine, you are using an axle motor to rotate the engine. If you want to see some spring engines, do a search here on Algobox and you will see quite a lot of them. The way to make a spring unstable is to give it a slightly negative damping value. Not too much or the spring will go nuts and die!

finns -- I remember I tried to teach you how to make a spring engine about a year ago. I see that you didn't learn a thing since then.

This is really cool! Nice job a_bored_coder!

All of those things that you list as "glitches" in the scene are not glitches. You are experiencing weird things happening because you are a noobie to Algodoo and simply do not understand how to configure or how to use those features that you are complaining about. For example:

1. Broken cloud generation. I have no idea what you are talking about. The clouds look normal to me.

2. Axle drift. That's because "hingeConstant" defaults to NAN (which means Not A Number). If you change that to +inf (infinity) the hinge (aka axle) will become much more stable.

3. Rotational axle drift. There is a number of issues here. For one, you have the gear and the sign overlapping each other. Multiple objects that have the same collision layers activated will go crazy. It's like two people trying to occupy the same space at the same time. It just doesn't work! The other issue (and its fix) is similar to complaint #2.

4. Broken brush. It ain't broken. You are simply expecting too much from it. Learn its limitations (as with all other Algodoo tools) and you will be able to use them properly.

5. Floating Point (type in pos "100000"). That makes no sense at all. Pos is an array consisting of X&Y values. Setting it to "100000" will cause weird things to happen!

I suggest that you read through the Algodoo FORUM. Although it's no longer active, there is a lot of good information that you can learn from especially if you are interested in Thyme Scripting.

FYI Algodoo was first published in 2009, and finally became available to purchase a couple of years later. The company (Algoryx) realized that, although it was popular by that time, people were not willing to purchase it and so they decided to give it away for free. The company makes most of their profits from other very sophisticated 3D simulation software that are used by governments, universities, and many large corporations. Algoryx is planning on updating Algodoo some time in the future as time permits, but they were not able to provide a date. They have a large list of bugs and enhancements that people suggested over the years, but since they don't make any profit on it, they will work on updating it when they can spare the time and expense that it will take to do that.

In case you didn't know, I am the current Admin here on Algobox. I will let everyone know when the company updates Algodoo.

I'll delete my last comments in which I criticized your spelling.

NoenD_io -- Didn't you read my previous comment? It explains the answer to your question.

Click the arrow that's left side of the Pause/Run button. OR, the scene will automatically pause after the monster kills you.

Nice work on the scene!

I'm familiar with electrical low pass, high pass, and band pass filters but using those filter concepts for thermal control is new to me. It does make sense, though. My home heating/cooling thermostat probably makes use of those filters for more consistent and smoother heating and cooling.

Suggestion: I think it would be interesting and educational to create a scene that shows the effects of all three types of filters that I mentioned above.

"The filters in your heating system are for collecting dust. "

Quick, I need to write a comment before I forget what to write.

I need to too.

I'm glad to see you're back posting on Algobox again!

Thanks, henrystj!

Hi richard1,
You did a really nice job on the ragdoll but there is one issue that can easily be fixed. Each time I press the J key, the ragdoll shoots up in the air like a rocket! You have way too much thrust from too many thrusters. I think I counted six thrusters, but you really only need one. Here is what I did to improve his jumps. First, I found all thrusters (except for the one under his neck) and set their thrust to zero. You can delete them if you want to. Then I set the thruster located below his neck to 16000. The ragdoll has plenty of upward thrust from one thruster. After you make those simple changes, save the scene and then edit the scene currently on Algobox by uploading the modified version of it. I think you would agree that his jumps are much better and controllable.

Please understand that I am just making a suggestion. You do not have to do it if you don't want to. Maybe you want the ragdoll to shoot up to the sky like a rocket!

Let me know if you have any problems with this or any questions.

Xray, Algodoo Admin

That's awesome! I believe you will have a very successful and rewarding future in aviation. I did most of my personal flying during my younger days after I was discharged from the US Navy. Although I have a commercial pilot license, I never worked as a professional pilot (long story). My life took me in a different, but also rewarding direction. I've never flown a helicopter but that's one of the things on my bucket list!

I hope to see more aviation related Algodoo scenes from you in the future!

Cool!

Thanks!

I have only one word to say about this: IMPOSSIBLE!
