|
|
* When you hit space, you get enough upward velocity to go 1.25 blocks
|
|
* Then, you fall the remaining 0.25 to get on the surface, on block higher.
|
|
* Since parabolas are symmetric, the amount of time it takes to ascend up from 1 to 1.25
|
|
* will be the same amount of time that it takes to fall back down from 1.25 to 1.
|
|
* And the same applies to the overall shape, if it takes X ticks to fall back down 1.25 blocks,
|
|
* it will take X ticks to reach the peak of your 1.25 block leap.
|
|
* Therefore, the part of your jump from y=0 to y=1.25 takes distanceToTicks(1.25) ticks,
|
|
* and the sub-part from y=1 to y=1.25 takes distanceToTicks(0.25) ticks.
|
|
* Therefore, the other sub-part, from y=0 to y-1, takes distanceToTicks(1.25)-distanceToTicks(0.25) ticks.
|
|
* That's why JUMP_ONE_BLOCK_COST = FALL_1_25_BLOCKS_COST - FALL_0_25_BLOCKS_COST
