I've created a tool that can function as a pickaxe, axe or shovel; but for some reason it's harvesting specific blocks much slower than the effective vanilla tool does while harvesting other blocks at the same speed as the vanilla tool.

 

The slow blocks include Block of Coal, Dispenser, Note Block, Bricks, Obsidian, Redstone Ore, Monster Spawner, Stairs, Doors and Pressure Plates. I can't see any pattern in which blocks are slow and which are normal speed.

 

My code can be found here: 1.7.10, 1.8.

 

Does anyone know what's going wrong? Is there some vanilla method I need to implement?

Have you tried to override ItemTool.getStrVsBlock()?

In 1.8,

Item#getStrVsBlock

is only used in

Item#getDigSpeed

(which

ItemTool

overrides to use tool classes) and

InventoryPlayer#getStrVsBlock

(which isn't used anywhere).

 

In 1.7.10,

Item#func_150893_a

(the equivalent method) is only used in

EntityPlayer#isCurrentToolAdventureModeExempt

(which should use my override of

Item#canHarvestBlock

first) and

Inventory#func_146023_a

(which again isn't used anywhere).

Here is the code for a custom tool that i made. Ignore the most part of the code and check what may help you. By the way this is for 1.7.10

I found the source of the problem: not all blocks have a harvest tool/level set, so you need to override

Item#canHarvestBlock

and

Item#getDigSpeed

to check the block's

Material

like the vanilla tools do.
