This is a ~~completely serious~~, totally ~~not~~ a joke mod that adds a 0.0001% chance to stub your toe every time you walk or run from block to block. This chance is doubled when you are walking up blocks without jumping (ex: walking up stairs/slabs, stepping up from farmland/paths onto a fullblock.

When you stub your toe, you are inflicted with a status effect that slows you down and may temporarily disable your ability to sprint or even move.

This mod is inspired by a Starbound mod with the same name that effectively does the same thing.

There are 3 different status effects that can be applied when you stub your toe, which one is actually applied depends on how fast you were moving when you stubbed your toe.

The first status effect is called "Hurt Toe" and is applied if you stubbed your toe at walking speed, it reduces your movement speed by 75% for 65 seconds.
The second status effect is called "Swollen Toe" and is applied if you stubbed your toe at sprinting speed, it reduces your movement speed by 75% and disables your ability to sprint for 20 seconds. After the 20 second period is up the first status effect is applied.
The third status effect is called "Where is my toe?" and is applied if you stubbed your toe at any speed faster than sprinting, it completely imobilizes you for 5 seconds. After the 5 second period is up, the second status effect is applied.

If you have the ParCool mod installed, you will be forced into a roll when you stub your toe. This can be disabled in the configuration, and ParCool is not required for the mod to function (you just won't do a roll after stubbing your toe...)

The mod will create a file called stubyourtoe.toml in the config folder which can be used to configure the mod.
The default contents for the file can be found below:

#The percent chance that a player will stub their toe when crossing the edge of a block.
#Range: 4.9E-324 ~ 100.0
