Jump amount control by holding down button longer?

bladeolson

I have created a jumping character. Right now if I push "jump" while touching the ground it sets attribute to "jump" and the jump sequence is initiated.

I set the Y Linierar velocity of the character to for .25 seconds to 300. This creates a nice jump. So far so good.

However, I am wondering has anyone implemented a jump that will for example give more jump "power" if the jump button is held longer? So short taps would be a short jump and holing it down would jump to a preset max jump? I looked for examples and the closest thing I could see was traffic Ninja.

I would appreciate some ideas.

Try using the "otherwise" part of the rule.

Lemme check an old template, but I think I might just have the thing for you...

Yep. Try this out: http://img407.imageshack.us/img407/2483/helpa.png. Needs tweaking, but will work.

thanks Kamazar, but not sure how that is different from what I have. I see you do not have run to completion checked , does that make any difference?

Kamazar

I think so. Since it isn't forced to accelerate for the entire 0.5 seconds, whenever you let go, it just stops.

Crazybreadman

yes, unchecking the 'run to completion' box is how to do it.

bladeolson

thanks guys, I tried that but my guy either jumps like 1 inch or 1 million feet. Any suggestions on good settings?

Kamazar

Apply a max speed. Should help.

Nice to see you back Kamazar

I've missed you

the key is to have him always accelerate down unless you jump. this is to counteer the physics engine.

then dont stack it the "move up"

like they said uncheck run to completion

bladeolson

Thanks James. I actually have been not using gravity in my game. Just applied a downward acceleration to the actor always.

So I tried the suggestions and it still is not working right. When I uncheck the run to completion button the guy just jumps a couple inches off the ground. If I increase the acceletation amount he jumps too high. So I tried to apply a max speed and that does not seem to be helping.

My Rule for Jumping also has two requirements 1 is "jump" is true ( button pressed ) and the 2nd is actor is "on the ground"

I am wondering if I have this kind of attribute then trigger him to jump he is no longer on the ground anymore so the longer keypress is not working?

Last thing, how do you counteract the goofy movement in the air while jumping. Meaning, if you jump to the right you can still move to the left in the air , feels odd. What do you guys think?

thanks for the help by the way. attached is screen shot from my project

you could find out at what time in the jump you want it to speed up so lets say 0.5 seconds after press then put
(other wise)
timer=0.6
change velocity to 450
and then put slightly more until you find what increase you want
