Algodoo

Yes, you need to use a real browser instead of that useless Algodoo browser. I think you will like doing things here on Algobox a lot better when using a real browser like FireFox or Chrome, etc.

I know. I made that last comment back in January 2021 (11 months ago) and he never replied to it. Oh well....

JP - Yes to all. Take a look at my scene: Electronic Circuit


I see that you have a lot of questions concerning Thyme Scripting, so I suggest that you check out the heading "Thyme Scripting" in the Algodoo Forum. There's a lot of good information there but you will have to put in the time and effort that's required to do the research.

JP - Yes, you can write a delay that will hold off a single command or procedure for N number of seconds. I do it all the time in many of my own scenes.

I must admit that your scene is better than mine in many ways, and the most important way is the fact that your character spacing and dot-dash timing are more accurate than they are in my scene. Excellent job!

My natural Morse code decoding ability has gotten rusty over the years, but I can still copy it with pen and paper without error at about 20 WPM. Back in my Navy and Ham Radio days I was able to copy about twice that speed and could send three times that speed with a Vibroplex Bug.

I was thinking that an interesting project for either one of us would be to make a scene that uses a Vibroplex Bug (mechanical keyer). It uses weights, springs, and electrical contacts to form dots and dashes. It's basically an electrical switch controlled by a person's hand. If interested, search on YouTube for "Vibroplex Bug" and you will see lots of videos that show it in operation. If you decide not to do it, then I might take a stab at it. Let me know what you think of it.

Thanks

ScienceSimulations - Yes, that's right, but some users make the mistake of announcing in the scene or in the scene description "Results are listed in the comments", or "Vote for your favorite athlete in comments", or those sorts of messages. Scenes with those kinds of alert messages in the description or in the scene itself are forms of announcements which are not allowed.

There are many different ways to make a time delay, and using timeToLive is probably the simplest.

I'm not sure what you mean by "a bit shorter". If you mean less than one second, that's easy to do. For example:

Set timeToLive = 1.0

Then where you need the delay do this:
timeToLive <= 0.25 ? {timeToLive = +inf; Do whatever you need here after delay period}:{}

NOTES: 1. You need to stop the timeToLive by setting it to infinity before it reaches zero if you don't want the geometry to die.
2. Never test for an exact time. Always use <= or >=. If you do only =, Algodoo might skip over the exact value you are waiting for and the timer will continue to run down until it times out. By using <= it ensures that the timer will stop when you need it to.

There are other ways to make timers which you can find by digging through my scenes or others that use a lot of Thyme Scripting.

Faytree -- That contest was posted FIVE years ago! Do you think anyone cares about it now?

By the way, your electrical power values make no sense! There is no way you can get over 400KW from three little 2Ah batteries. Impossible!

Good points!

Nice work.

I recall my first experience with a slide rule was back in the Stone Age when I learned how to multiply by adding logs (not the wooden kind). Then when calculators became affordable I repurposed my slide rule as a back scratcher (and not a very good one).

I found that vinodril's slide rule moves more like a real one by increasing the air friction, and the air friction multiplier for the slide and for the cursor. With the right values of air friction, those components no longer act like skates sliding across an ice rink. I also increased the pull force of the drag tool which helped.

Why not wait until the game is completed rather than posting non-working versions of it as you add things to it? No one wants to play a partially made game that hardly does anything correctly!

Where does it say I'm an M.E? All I see on that page are technical engineering type scenes that were made by YOU. (BTW - No I am not an M.E. Most of my professional work has been developing digital circuits for embedded 8-bit computer boards in industrial and medical equipment. So, my expertise is electronics design and 8-bit assembler code for the Intel 8085 uP back in the 1980's and 1990's). Yes I am an "old timer".

I believe that's caused by a bug in Algodoo. It has happened to me a few times over the years. I think that it happens when you try to use an invalid data value for some of the variables. For example if you try to enter text for a variable that expects an array (such as POS), it might display {Bad} and then crash the program. When that happens just relaunch Algodoo, and it should show that variable with a proper value. It has never caused any long-term or permanent damage to Algodoo or to my computer.

We used to use controlleracc like postStep because postStep was added at some later date after Algodoo first came out. You will see that in many of the older scenes in the Algobox archive (probably before 2012 or thereabout).

Concerning custom (also known as Local) variables, it depends if you used them like a called subroutine, or like a function which you can pass data to. If you use a local variable as a called subroutine, then just show the name of the variable in your postStep script. For example if you create a subroutine that does some calculation and you named it _sub, you can call it in postStep like the following:

temp >= 17 ? {_sub}:{}

Read the first couple of posts in the "Thyme Scripting" heading in the Algodoo FORUM for information the explains how variables and functions are created and used. There's a lot of good information there. Way too much to explain here in comments.

Okay, I see what cause my confusion. In the first sentence of your comment you addressed me: "I see that you, Xray, and I are all old timers." Then in the very next sentence it appeared that you were still addressing me with a PS: "P.S. I see that you are a Mechanical Engineer. Check out Algodoo for Engineering." Now I know you were addressing vinodrai. It's ambiguous. Just a bit more than an old-timer can handle. LOL

How can you say it's playable and is a great game? When I try to play it, it does virtually nothing. Only one clickable button works but it spazzes out with rising numbers and a crazy bar graph that oscillates back and forth! There are no directions for how to play the game and no explanation of control keys. It's barely functional at all. Don't you see that?

Okay, JustJacob, since user Gougou doesn't like to comment, I will ask you this:

If this game is "fully playable" as you stated then please explain to me how the game is played. What items in the game must I click on, and what is the strategy for winning the game? I haven't been able to figure those things out just by attempting to play the game but apparently, you have. So, please explain in detail how this game works.

Nice additions to Vinodrai's scene.

As a side note, I happen to be a person who reveres earthworms for their many benefits to the natural world. They may look slimy and disgusting, but most people don't realize how truly important they are to us all in helping to maintain the balance of nature.

If anyone wants to learn more about the importance of earthworms, here's a good starting point: Earthworms

People like you and me are simply not understood.

Just curious, why did you post this scene on Algobox? Don't you know that you can test your scenes on your computer without having to upload them to Algobox?

What you are asking is not simple to do. It requires a working knowledge of Thyme Scripting in order to determine where the car will spawn, how large the car is, as well as other parameters that determine how the car moves and reacts to external events (such as collisions). If you have no experience with or knowledge of Thyme scripting, then I would advise you to first learn that before attempting the kind of game that you wish to make. You can learn about Thyme scripting by reading posts in the Algodoo Forum under the heading "Thyme Scripting" and by loading other people's scenes to understand how they did certain things. I realize this is not the answer you were looking for, but it is the truth.

Ban you??? I didn't say anything about banning you! People only get banned when they break the rules. If you didn't break the rules then you have nothing to worry about.

Because of the script you added in the circle's postStep event you are forcing all of the circle's parameters to have fixed values. What's the point in doing that?

Nice improvements. Even the castings look realistic. Awesome!

Good job on the scene!

Most people don't realize how critical this problem is in the real world. Our oceans are cluttered with plastic rubbish and chemical pollutants mostly caused by people mindlessly dumping their garbage and industrial waste. It has to stop before we will all suffer the consequences.

做得好！ (well done!)

I wrote this comment 'cause I was bored.

There are a large number of pinball machine simulations in Algodoo, many of which are ones that I made. If you would search on the word "pinball" you will find out how many there are!

Creating a realistic pinball machine simulation is not easy to do. A finished and complete game would have digital scores, realistic bumbers that flash when hit, and other such things. It's a lot of work which cannot be done properly in a day or two, so I am looking forward to see how yours will turn out.

Nice job! The hydraulics are smooth and the machine moves without any problems.

The only odd thing that I noticed is that when the hydraulic rams extend past the limits of their movement, they reverse direction! Up becomes down and down becomes up for example. That sort of thing doesn't happen with a real back hoe. Except for that, you did an excellent job on it!
