[1.8] [Solved] crash onImpact splash potion

Glistre · August 14, 2016

Is the problem I am having because of missing texture or the onImpact method? NPE...

What is line 122.

Glistre · August 14, 2016

AxisAlignedBB axisalignedbb = this.getBoundingBox().expand(4.0D, 4.0D, 4.0D);

Animefan8888 · August 14, 2016

What does getBoundingBox() return and is it ever initialized?

Choonster · August 14, 2016

Entity#getBoundingBox

always returns

null

unless the

Entity

subclass has overridden it (only

EntityBoat

and

EntityMincraft

override it to return a non-

null

value in vanilla).
