Class ChunkCollision

java.lang.Object

net.malisis.core.util.chunkcollision.ChunkCollision

public class ChunkCollision
extends java.lang.Object

This class is the entry point for all the chunk collision related calculation.
The static methods are called via ASM which then call the process for the corresponding server or client instance.

Method Detail

getCollisionBoxes

public void getCollisionBoxes(net.minecraft.world.World world,
                              net.minecraft.util.math.AxisAlignedBB mask,
                              java.util.List<net.minecraft.util.math.AxisAlignedBB> list,
                              net.minecraft.entity.Entity entity)

Gets the collision bounding boxes for the intersecting chunks.
Called via ASM from World.getCollisionBoxes(Entity, AxisAlignedBB)

Parameters:

world - the world

mask - the mask

list - the list

entity - the entity

setRayTraceInfos

public void setRayTraceInfos(net.minecraft.util.math.Vec3d src,
                             net.minecraft.util.math.Vec3d dest)

Sets the ray trace infos.
Called via ASM at the beginning of World.rayTraceBlocks(Vec3d, Vec3d, boolean, boolean, boolean)

Parameters:

src - the src

dest - the dest

setRayTraceInfos

public void setRayTraceInfos(Point src,
                             Point dest)

Sets the ray trace infos.

Parameters:

src - the src

dest - the dest

getRayTraceResult

public net.minecraft.util.math.RayTraceResult getRayTraceResult(net.minecraft.world.World world,
                                                                net.minecraft.util.math.RayTraceResult mop)

Gets the ray trace result.
Called via ASM from World.rayTraceBlocks(Vec3d, Vec3d, boolean, boolean, boolean) before each return.

Parameters:

world - the world

mop - the mop

Returns:

the ray trace result

canPlaceBlockAt

public boolean canPlaceBlockAt(net.minecraft.item.ItemStack itemStack,
                               net.minecraft.entity.player.EntityPlayer player,
                               net.minecraft.world.World world,
                               net.minecraft.block.Block block,
                               net.minecraft.util.math.BlockPos pos,
                               net.minecraft.util.EnumHand hand,
                               net.minecraft.util.EnumFacing side)

Checks whether the block can be placed at the position.
Called via ASM from ItemBlock.onItemUse(ItemStack, EntityPlayer, World, BlockPos, EnumHand, EnumFacing, float, float, float) at the beginning.
Tests the block bounding box (boxes if IChunkCollidable) against the occupied blocks position, then against all the bounding boxes of the IChunkCollidable available for those chunks.

Parameters:

itemStack - the item stack

player - the player

world - the world

block - the block

pos - the pos

side - the side

Returns:

true, if can be placed

Parameters:

world - the world

state - the state

updateBlocks

public void updateBlocks(net.minecraft.world.World world,
                         MBlockState state)
