Ведро....

BlesseNtumble · 4 Апр 2015

Создал жидкость, сегодня попробовал сделать ведро.
Сделал, все хорошо, кроме одного момента:

При ПКМ моего ведра, крашит клиент:

Актуально.

tox1cozZ · 5 Апр 2015

Может быть блок равен нулл?
Врятли конечно, но проверь.

BlesseNtumble · 5 Апр 2015

Item bucket = buckets.get(block);
if (bucket != null....

а это разве не проверяет на нулл блок?

tox1cozZ · 5 Апр 2015

Посмотри 138 и 203 строку в ведре.

BlesseNtumble · 7 Апр 2015

if (!p_77659_3_.canPlayerEdit(i, j, k, movingobjectposition.sideHit, p_77659_1_))
{
return p_77659_1_;
}

и

else
{
if (!p_77875_1_.isRemote && flag && !material.isLiquid())
{
p_77875_1_.func_147480_a(p_77875_2_, p_77875_3_, p_77875_4_, true);
}

p_77875_1_.setBlock(p_77875_2_, p_77875_3_, p_77875_4_, this.isFull, 0, 3);
}

Непонимаю....

Глянул как реализованы ведра в других модах, так у меня почти так-же.
Хандлер вообще не используется.

А почему критует при ПКМ кастомным ведром не могу понять...

hohserg · 8 Апр 2015

А он у тебя extends Item или extends ВанильноеВедро?
Лучше сделай второй вариант, только переопредели метод OnRightClick

Открытая Математика

Ведро....
