Fire around player.

Hey Bukkit,

I was wondering how to spread fire around a player on ground?

Here a example of my idea with picture: (It can with different radius, You know.)


Greeting,
Ronald.

 

for loops

 

Really informative reaction...

Instructions or some code is a better reaction..

 

Sorry haha so what exactly do you want to do? I'm assuming something like use a command and a square of fire is created around you?

 

I want to have: If a player (For example myself), use /fire or any trigger maybe event, then spawn a square or circle of fire around the player (on the blocks around him), i don't know to code that. but i know i must using for loops.

 

get the aerea and start replacing all air blocks in fire ones. Maybe ill post some code later

 

DusRonald I can't seem to think of a clean way to do this, to generate a square you would just increment x and z from a location but that would create a square where the player is at one of the corners. The only way I can think of to do it is have 4 small squares incrementing both x and z, incrementing x while negatively incrementing z, negative incrementing both, and negative incrementing x while incrementing z. Sorry if that is confusing but heres a link I found too http://pastebin.com/AspGRgAD

 

Replace the air blocks is easy, but how get the area?

 

you have to think mate, think to logic and your sexy math prof

 

I don't understand the logic of Java...

 

DusRonald yolo it then

 

Code:java

mPoint = p.getLocation().add((double)radius -1,(double)radius -1,0); // You find the first corner

 

Marked as useless reaction.

 

check this http://www.mathopenref.com/coordbasiccircle.html

 

And the second corner?

What..? I don't understand that..

.subtract(same thing) you find the opposite corner

 

4thegame3 Can you give me a full example code?

Bytheway: Thanks for help.

 

DusRonald maybe something like
Location safeblockloc = p.getlocation().substract(0,1,0);
Block block = safeblockloc.getblock();
block.settype(material.grass);
safeblockloc.add(1,0,1);
for(int i = 0; i <= 3; i++){
Block blocksonfire = safeblockloc.add(1,0,1).getblock();
blocksonfire.setType(material.netherrack);
}
//the fire on top you figure out i wrote this on a tablet so too hard to write code from a tablet or phone

 

For a circle, you'd want something like:

Code:java

 
Location playerLocation = p.getLocation();
int centerX = playerLocation.getBlockX();
int centerZ = playerLocation.getBlockZ();
int radius = 5; // or whatever you want
int rSquared = radius * radius;
for (int x = centerX - radius; x <= centerX + radius; ++x) {
    int xSquared = (x - centerX) * (x - centerX);
    for (int deltaZ = 0; xSquared + deltaZ * deltaZ <= rSquared; deltaZ++) {
        // Do something with these coordinates:
        // (x, playerLocation.getBlockY(), centerZ + deltaZ)
        // (x, playerLocation.getBlockY(), centerZ - deltaZ)
    }
}
 

 

im working on a code that calculates every point of a cyrcle perimeter, but it will take time idk if ill ever end it.

 

No, it's not.

Okay.

DusRonald what you mean no its not

 

It's not really hard to type on a mobile device.

 

DusRonald ok so have you tried the code i put or you planing on changing the topic to "is it easy or hard to type on a mobile device" ... not a mean comment just saying xD

 

See this topic: Click here.
Link from above: http://forums.bukkit.org/threads/poll-write-code-on-mobile-device-is-hard.311894/

Have anyone Craftbukkit.jar?

You do not use:

Code:java

int centerZ = playerLocation.getBlockZ();

i have found this

Code:java

public static Point PointOnCircle(float radius, float angleInDegrees, PointF origin)
    {
        // Convert from degrees to radians via multiplication by PI/180     
        float x = (float)(radius * Math.Cos(angleInDegrees * Math.PI / 180F)) + origin.X;
        float y = (float)(radius * Math.Sin(angleInDegrees * Math.PI / 180F)) + origin.Y;
 
        return new Point(x, y);
    }

 

Sure I do. In the comment where I say use these coordinates. I add and subtract deltaZ to and from centerZ to get the coordinates.

[edits: not so much syntax, looks bad]

 

Can you give me full code of that? Include set the block.

 

DusRonald

Figure it out for yourself, spoonfeeding is not desirable. The JavaDocs for Bukkit are easily available, and many threads have been made on the subject.

 

I'm lazy XD
Tomorrow i figured out.
