Basic Marble Blast Coding Q&A

OK, thanks!

Suppose I wanted to add on to the onMissionLoaded function in MBP, but only in one MIS file. You can do this in Java by using super(), but can you do it in TS? And if so, how?

No problem.

I want to also point out that this is an awesome way of asking for a coding question, when comparing it to another language. (Mind you I know c++, Java, VB, TS, PHP)

Thank you for asking it well. I was able to answer it right away

Heh, no problem. I've always been better at pure coding languages (C++, java, etc.) than scripting (TS, python...). Don't ask why.

Also, on a related note, is onMissionLoaded called whenever the marble goes OOB and respawns, or just when you click the Play button in the menu and the marble spawns for the first time?

Nvm, I figured it out.

just fyi onMissionReset is used for your scratched out part.

and ah okay.

Not really a coding question as much as being curious:

Why does the Random Force (fric: -1, res: 1) do the random force, and go in one direction?
Also the phenomenon of the jump and go forward thing.

1. it just forces the marble to go in its opposite spin direction, so applies a negative angular velocity?? I think.

2. what?

To avoid the random force, you can jump and hold W (or W+A/W+D) to go in that direction.
(it also works going backwards)

yeah because it reverses the reversed angular velocity.

Hey, i've been coding some stuff for some days and i have some questions.

1. How to put the informations of a mission (e.g the description) into a variable (only with the .mis directory)?

2. What are the arguments of the moveMap.bindCmd functions? Especially the third one since i had to leave it empty to make my code works.

3. What is the function to end a game? (e.g disconnect(); but it send you to the playMissionGui, is there any function that will just destroy the game?

4. Why can i call the loadMission(); function while playing a mission without making the game crashes like the doCreateGame(); does?

5. Is there any function that makes a delay (the schedule function actually don't wait the specified time to read the next line).

6. What does the tickPeriodMS = 100; stands for in the trigger.cs file?

Thanks

1. %blah = MissionInfo.desc; mis directory loop through files and create a new file object, and read it.

2. leave it blank, idunno but you shouldn't need it

3. modify disconnectCleanup() to not send you there (serverconnection.cs)

4. docreateGame IIRC creates a server, loadmission doesn't.

5. you have to use schedule

6. interval of the onTick() callback is called when an object is inside of the trigger

It's only working when the mis is loaded, i'd like to use it for a GUI.

How? It doesn't wait for the specified time to read the next line of code...

Thanks anyway

from MBElite:

Code:// Jeff: grab mission info
function getMissionInfo(%file) {
%fo = new FileObject();
%inInfoBlock = false;
%egg = false;
%gems = 0;
%info = ;
if (%fo.openForRead(%file)) {
while (!%fo.isEOF()) {
%line = trim(%fo.readLine());
if ((!%inInfoBlock) && (strStr(%line,new ScriptObject(MissionInfo) {) != -1)) {
%info = new ScriptObject() {;
%inInfoBlock = true;
continue;
} else if ((%inInfoBlock) && (strStr(%line, } != -1)) {
%info = %info NL %line;
%inInfoBlock = false;
continue;
} else if (%inInfoBlock) {
%info = %info NL %line;
continue;
}
if (strStr(%line,EasterEgg) != -1) // Jeff: easter egg!
%egg = true;
else if (strStr(%line,Gem) != -1) // Jeff: gems!
%gems ++;
}
%fo.close();
}
%fo.delete();
if (%info $= )
return -1;
eval(%id= @ %info);
if (!isObject(%id))
return -1;
%info = %id.getId();
%info.file = %file;
%info.easterEgg = %egg;
%info.gems = %gems;
%info.schedule(5000,delete);
return %info.getId();
}

usage:

%missionInfo = getMissionInfo(%file);
%desc = %missionInfo.desc;
%artist = %missionInfo.artist;
// ect.

$eventId = schedule(time, 0, function, args);

alternatively for objects:

%obj.event = %obj.schedule(time, method, args);

Thank you, Jeff! I will try it

How do you modify the name of the times, like if I want to change You have beaten the GOLD time! to You have beaten the LOL time!

marble/client/scripts/game.cs

iirc function name is:

reformatGameEndText

Thanks!

@Alexis: also, if you're looking for info on a level that shows up in PlayMissionGui, those variables already exist--the group PlayMissionGroup will contain groups of the ScriptObjects for all of your levels, grouped by category (e.g. MTYPE_Beginner has all of the Beginner levels). Each ScriptObject will also have a file field containing the path to the mission file.

How do you make gravity buttons (ratios)?

Example: O = a ratio

Gravity

O Low
O Normal
O High

In the GUI editor or by manually editing a .gui file, you can set a button's buttonType to RadioButton. RadioButton buttons in the same SimGroup will work together (by letting you only press one). There is a GuiRadioCtrl for them, but it looks very generic; I'd recommend using GuiBitmapButtonCtrl if you want to stay in the style of your modification (it will still work as expected). You can use the variable or command fields to grab the input from them (e.g. by setting a different variable for each and testing which is set, or by giving each a command to change the setting).

Another question: how do you male items (gems, power ups) have particle effects?

Gems have a gender?!

DISCRIMINATION AGAINST FEMALE GEMS!!!

on a serious note, make custom code and in the gem::onAdd function schedule a particle to spawn. Also please note that coding question and answer does mean in my opinion that you try to make an attempt to code, not entitlement to code.

oops typo fail I meant to say make. *laughs*

EDIT:

Yet another question(I've got a lot)

I know the basics of particle(changing the colors, sizes) but how do you do the cool stuff like in marble blast fubar?

With magic and editing the particle fields. There isn't much more than editing fields when it comes to particles. See Aayrl's particle guide in the MBDK or Vault MBDK.

Thanks for all the help

Bump, but I have a question.

Is it possible to return the coordinates of the marble? Such as if I wanted to measure how far the marble has traveled, how would I do that?

%pos = localClientConnection.player.getPosition();

returns a string x y z

to get each coordinate use the following

%x = getWord(%pos, 0);
%y = getWord(%pos, 1);
%z = getWord(%pos, 2);

if you want the length of the position vector use the following

%length = VectorLen(%pos);
