Jump pads would be blocks that launch you upwards but it would only be about 10 blocks high.
You could make new jump pads that let you go 10 blocks higher. There would be 5 jump pads in all. Jump pad tier 1 - 10 blocks high. Jump pad tier 2 - 20 blocks high. Jump pad tier 3 - 30 blocks high. Jump pad tier 4 - 40 blocks high and last of all jump pad tier 5 - 50 blocks high. the crafting recipe would be something like this minecraftrecipedesigner.com/creations/370012.png. The next tiers would be adding 3 or 4 pieces of iron to the tier below it. Gravitation pads would do what most long fall drops do, but it wouldnt slow you down at the bottom, it would just let you not get hurt by falling. the gravitation pad would be crafted like the picture above.
Thank You!
