[N Help/Advice Modding] Detection Player->specificBlock [solved]

[opssemnik]

because the iterator of the list its not playerEntities, if u wanna get the player object just do Minecraft.getMinecraft().thePlayer, but if u wanna the player iterator you must do

Iterator iterator = Minecraft.getMinecraft().theWorld.playerEntities.iterator();

while (iterator.hasNext()){

        Object obj = iterator.next();

        if ((obj instanceof EntityPlayer) && !((EntityPlayerMP)obj).username.isEmpty())

        {

                // Do Stuff!

        }

}

yeah saw it a moment ago^^

 

so this works:

 

                       

AxisAlignedBB var4 = AxisAlignedBB.getBoundingBox(plX, plY, plZ, plX + 1.0D, plY + 1.0D, plZ + 1.0D).expand(4D, 2D, 4D);
	       List list = Minecraft.getMinecraft().theWorld.getAllCollidingBoundingBoxes(var4);

            Iterator var6 = list.iterator();
            AxisAlignedBB var7;
            
            if(list != null)
            while (var6.hasNext())
            {
                var7 = (AxisAlignedBB)var6.next();
            }

 

i get these boxes: box[-295.0, 68.0, 277.0 -> -294.0, 69.0, 278.0], box[-295.0, 69.0, 277.0 -> -294.0, 70.0, 278.0],...

now i have to find out if there is a torch under it do you know a easy way?

[opssemnik]

found another way

EntityPlayer pl = Minecraft.getMinecraft().thePlayer;

if(Minecraft.getMinecraft().theWorld.getBlockId(pl.posX, pl.posY, pl.posZ) == Block.torchWood.blockID){

//do stuff

}

[Ghoul159]

yeah but the problem is i need an area / radius around the player... so  only if the player is near the torch... do stuff...

 

btw thanks for your dedicated help!

[opssemnik]

EntityPlayer pl = Minecraft.getMinecraft().thePlayer;

if(Minecraft.getMinecraft().theWorld.getBlockId(pl.posX, pl.posY, pl.posZ) == Block.torchWood.blockID){

//do stuff

}

if(Minecraft.getMinecraft().theWorld.getBlockId(pl.posX++, pl.posY, pl.posZ++) == Block.torchWood.blockID){

//do stuff

}

[Ghoul159]

EntityPlayer pl = Minecraft.getMinecraft().thePlayer;

if(Minecraft.getMinecraft().theWorld.getBlockId(pl.posX, pl.posY, pl.posZ) == Block.torchWood.blockID){

//do stuff

}

if(Minecraft.getMinecraft().theWorld.getBlockId(pl.posX++, pl.posY, pl.posZ++) == Block.torchWood.blockID){

//do stuff

}

 

this should work thanks alot!!!

 

havent thought about this way even its an easy one

[opssemnik]

im on my tablet, i dont now if works, but please tell if it works, i need to my mod too.

im on my tablet, i dont now if works, but please tell if it works, i need to my mod too.

 

i'll try that tomorrow and write if it works... have to go to sleep...^^

[Ghoul159]

ok got it working i think many people could use this so i'll write this short tutorial

plz give me a Thank you if my code was helpful and maybe write me into your credits if you just copy my code

 

This following code is used inside a clientSide TickHandler class:

 

inside of the tick:

		AxisAlignedBB var4 = AxisAlignedBB.getBoundingBox(plX, plY, plZ, plX + 1.0D, plY + 1.0D, plZ + 1.0D).expand(heatRadius, heatRadius, heatRadius);
	       List list = Minecraft.getMinecraft().theWorld.getAllCollidingBoundingBoxes(var4);

            Iterator var6 = list.iterator();
            AxisAlignedBB var7;
            
			int i = 0;
            if(list != null)
            {
            	for(int j = 0; j < list.size(); j++)
            	{
	            	if(StringToBlockID(list.get(j).toString(),"first") == Block.torchWood.blockID)
	            		System.out.println("FOUND TORCH!"); 
	            	if(StringToBlockID(list.get(j).toString(),"second") == Block.torchWood.blockID)
	            		System.out.println("FOUND TORCH!"); 
            	}

i got it workin ,i think many people could need this code so i'll share it here...

i don't know if there is an easyer way but this works

plz give me a "Thank You" if my code was usefull

 

the code compares if certain blocks are near the player...

 

The following code is in an clientSide TickHandler class:

 

in the onTick method:

			
                    //player coordinates
                    int plX = (int)Minecraft.getMinecraft().thePlayer.posX;
	    int plY = (int)Minecraft.getMinecraft().thePlayer.posY;
	    int plZ = (int)Minecraft.getMinecraft().thePlayer.posZ;
                    //the radius of your player->Block detection
                    double boundingBoxRadius = 3;                    

            //that it'll work only if the player is there
            if(Minecraft.getMinecraft().thePlayer != null)
    {
                    //set the box for collision detection with other boxes
                    AxisAlignedBB var4 = AxisAlignedBB.getBoundingBox(plX, plY, plZ, plX + 1.0D, plY + 1.0D, plZ + 1.0D).expand(boundingBoxRadius , boundingBoxRadius , boundingBoxRadius);
                    //get all colliding boundingBoxes with our var4 box
	    List list = Minecraft.getMinecraft().theWorld.getAllCollidingBoundingBoxes(var4);
            
                    //only work if theres something in the list
            if(list != null)
            {
                        //go through the list
            	for(int j = 0; j < list.size(); j++)
            	{
                                //send the current colliding box to get the blockID and compare it
	            	if(StringToBlockID(list.get(j).toString(),"first") == Block.torchWood.blockID || StringToBlockID(list.get(j).toString(),"second") == Block.torchWood.blockID)
	            		System.out.println("FOUND TORCH!"); //this does someting for each block that matches the compared block

            	}
                      }
            }

 

and this is my created method (also in the same class) to get the specific Block id:

public static int StringToBlockID(String line, String whichOne)
{
	//MADE BY Ghoul159
    	int posStart = line.indexOf("[");
    	int commaFirst = line.indexOf(",");
    	int commaSecond = line.indexOf(",",commaFirst+1);
    	int posEnd = line.indexOf("->");
    	
    	if(whichOne == "second")
    	{
        	posStart = line.indexOf("->")+1;
        	commaFirst = line.indexOf(",",posStart);
        	commaSecond = line.indexOf(",",commaFirst+1);
        	posEnd = line.indexOf("]");
    	}
    		
    	
    	String BlockX = line.substring(posStart + 1, commaFirst);
    	String BlockY = line.substring(commaFirst + 2, commaSecond);
    	String BlockZ = line.substring(commaSecond + 2, posEnd);
    	
    	int BlockPosX = (int)Double.parseDouble(BlockX);
    	int BlockPosY = (int)Double.parseDouble(BlockY);
    	int BlockPosZ = (int)Double.parseDouble(BlockZ);
    	
    	int blockId = Minecraft.getMinecraft().theWorld.getBlockId(BlockPosX,BlockPosY,BlockPosZ);
    	return blockId;
}

instead of creating strings and stuff, just create an object of the list, and then you check if the obj instanceof Block.torchWood

 

like

      //player coordinates
                    int plX = (int)Minecraft.getMinecraft().thePlayer.posX;
      int plY = (int)Minecraft.getMinecraft().thePlayer.posY;
      int plZ = (int)Minecraft.getMinecraft().thePlayer.posZ;
                    //the radius of your player->Block detection
                    double boundingBoxRadius = 3;                    

            //that it'll work only if the player is there
            if(Minecraft.getMinecraft().thePlayer != null)
     {
                    //set the box for collision detection with other boxes
                    AxisAlignedBB var4 = AxisAlignedBB.getBoundingBox(plX, plY, plZ, plX + 1.0D, plY + 1.0D, plZ + 1.0D).expand(boundingBoxRadius , boundingBoxRadius , boundingBoxRadius);
                    //get all colliding boundingBoxes with our var4 box
      List list = Minecraft.getMinecraft().theWorld.getAllCollidingBoundingBoxes(var4);
             
                    //only work if theres something in the list
             if(list != null)
             {
                  Object obj = list;//or list.iterator; or list.iterator.hasNext();    
                  if(obj instanceof BlockTorch){
                        
                          System.out.println("FOUND TORCH!"); 
                   }
              
                      
            }
