Nothing really special. Just some fireworks being shot up into the air and exploding on the way down. No sound effects due to size limit. I wanted to make it fancier but I just don't have the time. I wanted to randomize the fireworks coming from different mortars and some other things. But some things have come up and I am too busy to finish this.

But if you like it, enjoy. All the fireworks comes from mmf library or from a free animation website.

Happy Fourth of July

Here is the mfa. I removed the samples to reduce size. I had to zip it due to 1mb limit.

I dont understand. I am using the speech bubble extension and string extension, and I cant get the set text from string paragraph to work.

I have used speech bubble before, loading text from ini object. But now I would like to load from string. But I cant seem to get it to work. Could someone upload an example or just give the code to set text for speech bubble from string object.

Thanks

I am not understanding how the explosion effect is happening and all the balls and trails that follow. I just don't see it in the code. I don't know if something is hidden or there is something more about MMF that I don't know about.

I don't understand this alpha channel example. I have not used MMF professionally, so I am still learning. When I look at the code for fireworks I only see 5 lines of code. And in those five lines I don't see anything that is creating the effect. Line two makes no sense to me, why create just to destroy. Line 3 only creates one object, the light player, but it appears to create only one, but the example has many objects.

It just seems like there should be more lines of code, that I am not seeing or I just don't know. I don't understand what I am missing in understanding this example.

Any help, and instructions would be much appreciated.

Thanks

Well silly me. I don't know if I even want to admit this. But I was testing the third frame, so when I did that I clicked F7 to just run the frame. So when the frame was over it closed the frame. When I ran the whole application it did restart like it was suppose to.

Sorry guys.

And thanks for looking.

This program is designed to restart the application after the third frame is done playing. But when the third frame is over, the program closes down. I tried using go to frame one and it did the same thing. Is this a bug or is there something wrong with the code.

Its really all very simple code and has no extensions.

I removed unused variables and grouped events together.

This is amazing. I was looking over vector math conversion from 3d to 2d space and then I get an idea. So I looked back over the code and wow, I did it. No multiple quadrants. Just a couple of calculations to get a full screen of stars instead of 12 quadrants plus the calculation of each quadrant.

It only took an hour of clicking once I figured out that I was not using the k vector constant. Anways, here is the updated version. There is extra variables and could use commenting. I will update this thread again later with a cleaner code but for now here is the new and improved 3d star field example.

Well, I tried and tried to get various algorithms to work in MMF but to no avail and no one had any ideas. So I kept going back to Eliyahu 3d Space Example. The down side to that example as good as it is, is that it does not give a full screen of stars. I tried altering his code to get a full screen but nothing I did worked.

In the end what I ended up doing is using Eliyahu's 3d space example code and altered it to where I made 12 different quadrants. It was more coding than I was wanting. I wanted a more simplified code, but after 2 or 3 days of playing with this, this was the best I could figure out.

I did not want the perspective to be from a space craft traveling through space but rather a swivel turret on a space ship. I would have preferred to have a wider range of movement, but I am not going to code 18 more events to get a wider range of movement.

I have it to where you use the arrow keys to move around. Sorry about the counter in the picture. I deleted it from the program. I use counters to debug.

Well, I did some more searching in the forums and I finally found the answer. Its as simple as doing zero minus the number.

So, my expression is 0.0 + Random(100) / 100.0 * - (0-( Frame Height / 2) ) + 1

I need to change a positive number in my calculations to a negative number in the expression editor.

I have multiple calculations for coordinates.
So one calculation is 0.0 + Random(100) / 100.0 * ( Frame Height / 2 ) + 1
Then the next needs to have Frame Height / 2 - negative.
0.0 + Random(100) / 100.0 * - ( Frame Height / 2 ) + 1

In the expression editor using - as a negative or multiplying by negative 1 shows error.

Thanks

I am trying to create a 3d space travel in MMF from Timewasters space travel done in HTML 5. The web link is this - Please login to see this link.

My program starts off in the first loop to be like Timewasters, but when the stars are re-set to back, it all goes bad. And when stars get close to disappearing it goes bad also.

I have worked on this all day. I am hoping someone can see the code and help me understand where I am messing up.

I used a large red ball just so I could see better what is going on. That will be changed once I get things working correctly. I also will be having a total of three different kind of stars, but for now I just have one set coded, until I can get that set working correctly.

oops, I did .01 instead of 0.0. Its working now.

I think the answer is this 0.1 + Random(100) / 100.0. But even though it gives me decimals from .01 to 1, why does it give me numbers above 1. I am getting anything from 1.01 to 1.08.

I need to get a random decimal number between 0 and 1. How to do it in MMF.

Thanks

I am using the array object and it was my understanding that if I set the base index to 1 that the array's x index would be numbered from 1 - 10, not 0 - 9.

Please advise

Figured out a better way. I will use the array with the number of columns representing x and rows y.
Each value will be 1. To get the x y coordinate in multiples, I will multiply either array x or y by 32.
What ever coordinates I use, I will change the value to zero. I will test for only using the coordinates as long as the value is 1.

I want a look up table for screen x, y coordinates. For portability I am going to use Array object.

The x, y coordinates will be in multiples of 32. So what I was thinking is 2 columns and 140 rows.
I would have for the first column (screen x) 14 zeros for the first 14 rows and then fill the second column (screen y) with the 10 different values. I would then half to fill the remainder 4 rows with zeros. Then the next 14 rows would have 1's for and the second column as before.

This look up table is only needed at the beginning of the game for placing objects.

If there is a better Idea, please let me know.

Thanks
