Changing jump height

[The Ultimate DooMer]

I need to alter the player's jumping height without changing the gravity (which would screw up other effects). I remember something about LWM doing a 'cat jump' in one of her mods with a ThrustThingZ script, but I don't know how she avoided the problem of being able to jump in mid-air.

I need the jump to act exactly like the normal jump (in other words: no fixed delays), so is there some way to check whether or not the player is on the ground/in the air without putting sector actions in every single sector to change a variable?

You might be able to do it with some combination of:

http://www.zdoom.org/wiki/index.php?tit ... ctorFloorZ

But I'm not sure how you'd specify what sector to check for GetSectorFloorZ.

[The Ultimate DooMer]

Is the GetActorZ relative to the ground (like a thing's z-height) or is it the total co-ordinate like x and y?

[Graf Zahl]

It's absolute. But there's also a GetActorFloorZ so you can easily calculate the difference. Don't use GetSectorFloorZ because it might give incorrect results if you are standing over a dropoff.

As for the jump factor, that's unfortunately hard coded into the player classes, otherwise this might be much easier.

I thought that the jump was implemented with ThrustThingZ (correct term?).

Could you not simply use another to boost the effect?

[Cutmanmike]

Prehaps a sv_jumpstrength or player property for jumpings should be around?

[Risen]

...there's also a GetActorFloorZ...

Aha, so there is. That should be all that's needed, I think.

[The Ultimate DooMer]

GetActorFloorZ returns the highest floor point underneath the actor.

So that's basically what I'm after then? (if i have the script checking the difference between GetActorZ and GetActorFloorZ when the button is pressed and stopping the jump if it's above 0)

argh: what if the player is on a bridge or other thing?

[Graf Zahl]

Then floorz should come from the other thing's top.

[The Ultimate DooMer]

Which could be any height really (and with no way of telling the script that you're on a bridge, barrel etc.)

In short, we need a player property for jump height.

In short, we need a player property for jump height.

Most definitely!

Damnit, there's a lot of stuff I can't do for Serpent yet
