UE1:RJumpPad

About

This is class for classic Unreal Tournament '99. Based on JumpTarget 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.
