player.rayTrace not work..

UP

I think ray tracing should be able to work.

 

On the client side, I think you can use Minecraft.getMinecraft().objectMouseOver and check what it is (block or entity).

With the EntityItem does not work.

UP

show code?

MovingObjectPosition mop = player.rayTrace(40, 1.0F);

Entity ent = mop.entityHit;

 

Hi

 

This line in EntityRenderer.getMouseOver is probably the reason

 

                for (int i = 0; i < list.size(); ++i)

                {

                    Entity entity = (Entity)list.get(i);

 

                    if (entity.canBeCollidedWith())  // here -> can't collide with EntityItem

 

You might need to copy the code from EntityRenderer.getMouseOver into your own method and alter it.  Depending on what you're trying to do, if you want this to work on the server side you probably need to copy the code anyway.

THANKS!!!

Code:

public Entity getMouseOver(float partialTicks, double distance, boolean canBeCollidedWith){
Minecraft mc = Minecraft.getMinecraft();
Entity pointedEntity = null;
MovingObjectPosition rayTrace = null;

if(mc.renderViewEntity != null){
if(mc.theWorld != null){
rayTrace = mc.renderViewEntity.rayTrace(distance, partialTicks);
Vec3 positionVec = mc.renderViewEntity.getPosition(partialTicks);
double distanceToVec3 = distance;

if(rayTrace != null){
distanceToVec3 = rayTrace.hitVec.distanceTo(positionVec);
}

Vec3 lookVec = mc.renderViewEntity.getLook(partialTicks);
Vec3 posDistVec = positionVec.addVector(lookVec.xCoord * distance, lookVec.yCoord * distance, lookVec.zCoord * distance);
Vec3 tempVec = null;
double boxExpand = 1.0F;
List<Entity> entities = mc.theWorld.getEntitiesWithinAABBExcludingEntity(mc.renderViewEntity, mc.renderViewEntity.boundingBox.addCoord(lookVec.xCoord * distance, lookVec.yCoord * distance, lookVec.zCoord * distance).expand(boxExpand, boxExpand, boxExpand));
double vecInsideDist = distanceToVec3;

for(int i = 0; i < entities.size(); i++){
Entity entity = entities.get(i);

if(!canBeCollidedWith || entity.canBeCollidedWith()){
double borderSize = entity.getCollisionBorderSize();
AxisAlignedBB expEntityBox = entity.boundingBox.expand(borderSize, borderSize, borderSize);
MovingObjectPosition calculateInterceptPos = expEntityBox.calculateIntercept(positionVec, posDistVec);

if(expEntityBox.isVecInside(positionVec)){
if(0.0D < vecInsideDist || vecInsideDist == 0.0D){
pointedEntity = entity;
tempVec = calculateInterceptPos == null ? positionVec : calculateInterceptPos.hitVec;
vecInsideDist = 0.0D;
}
}else if(calculateInterceptPos != null){
double calcInterceptPosDist = positionVec.distanceTo(calculateInterceptPos.hitVec);

if(calcInterceptPosDist < vecInsideDist || vecInsideDist == 0.0D){
if(entity == mc.renderViewEntity.ridingEntity && !entity.canRiderInteract()){
if(vecInsideDist == 0.0D){
pointedEntity = entity;
tempVec = calculateInterceptPos.hitVec;
}
}else{
pointedEntity = entity;
tempVec = calculateInterceptPos.hitVec;
vecInsideDist = calcInterceptPosDist;
}
}
}
}
}

if(pointedEntity != null && (vecInsideDist < distanceToVec3 || rayTrace == null)){
return pointedEntity;

return null;
