Passable Leaves

Passable Leaves is a Minecraft core mod that makes leaves passable, which means that you can walk/fall through leaves instead of being obstructed by them.

The effect applies to all entities (including players, mobs, and items) and all leaves (including those added by other mods).

passableleaves {
    # The percentage of normal damage taken when taking damage from falling into leaves.
    # The damage will be reduced by a further 10% with the Jump Boost potion effect.
    I:"Fall Damage Reduction"=50

    # When falling into leaves, the (block) distance a player or mob has to fall before taking damage.
    I:"Fall Damage Threshold"=20

    # The reduced horizontal speed when passing through leaves. (% of normal)
    I:"Speed Reduction - Horizontal"=90

}

1.10 & 1.11

# Configuration file

leaves {
    # Higher values = more damage taken upon falling onto leaves.
    # For example, most blocks have a value of 1.0 (full damage).
    # Hay blocks have a value of 0.2 (20% damage).
    # Slime blocks & cobwebs have a value of 0.0 (no damage); 
    #  [range: 0.0 ~ 1.0, default: 0.0]
    S:"Amount of fall distance to keep upon falling onto leaves."=0.0

    # Higher values = faster speed. Set to 1.0 to pass through leaves without slowing down.
    # You normally want this to be the same as the rate of speed along the Z axis.
    #  [range: 0.0 ~ 1.0, default: 0.75]
    S:"Rate of speed when passing through leaves along the X axis."=0.75

    # Higher values = faster speed. Set to 1.0 to pass through leaves without slowing down.
    # This setting affects how fast you fall through leaves.
    #  [range: 0.0 ~ 1.0, default: 0.75]
    S:"Rate of speed when passing through leaves along the Y axis."=0.75

    # Higher values = faster speed. Set to 1.0 to pass through leaves without slowing down.
    # You normally want this to be the same as the rate of speed along the X axis.
    #  [range: 0.0 ~ 1.0, default: 0.75]
    S:"Rate of speed when passing through leaves along the Z axis."=0.75
