UE1:RJumpPad
About
This is class for classic Unreal Tournament '99. Based on JumTarget and JumpZModifier it calculates real jump velocity. In opposition to Kicker this class igoners player velocity. It was inspired by Jumppad from UT 2004;
Properties
Visible
- bool bDebugJump
- allows to change JumpZModifier in game (for debug purpose only)
- Actor JumpTarget
- jump target (eg. Actor'MyLevel.LiftExit0'
- float JumpZModifier
- jump z modifier is used for tweaking Jump, if needed
- sound JumpSound
- jump sound
- name JumpClasses
- clase able to use RJumpPad
Hidden
- vector RealJumoVelocity
- The actual, calculated, jump velocity.
