That specific example was a modified class the changed the jumppad to also add horizontal movement thru the air. You can use the vertical jumppad (use any vanilla game block you want ( dont need my custom jumpplate block model) as the jumppad and it will launch the zed high up. you can use blocks above like the tubes to redirect that motion. this is some xml to get started:
<block name="JumpPad">
<property name="Shape" value="ModelEntity" />
<property name="Model" value="#@modfolder:Resources/JumpPlate.unity3d?JumpPlate"/>
<property name="Collide" value="sight,movement,melee,bullet,arrow,rocket"/>
<property name="Class" value="JumpPad" />
<property name="StabilitySupport" value="true"/>
<drop event="Destroy" count="0" />
<property name="Material" value="Mwood"/>
<property name="ImposterExclude" value="true"/>
<property name="ImposterDontBlock" value="true"/>
<property name="CreativeMode" value="Player"/>
<property name="CanPlayersSpawnOn" value="true"/>
<property name="CanPickup" value="true"/>
</block>
