Inconsistent Jumping

mobileappconcepts

I've tried searching and looking at the wiki to no avail. I'm having issues getting a Mario style platform actor to jump consistently at the same height.

I've looked at the wiki and I want the uniform jumping but the example there seems incomplete. Could someone explain the process of making this work?

I have all the basic things working: platforms, moving platforms, gravity, left and right movement. It just doesn't feel right when the actor doesn't jump at the same height each time.

Have you tried putting a 90 to scene accelerate in a timer with run to completion checked?

That's what i've been using:

For 0.08 seconds w/ runto completion checked

Direction 90
Acceleration 10000
Relative to: Scene

It seems like roughly 3 of 4 jumps are accurate.

Anyone have any suggestions how to jump properly in a platform style game?

Here's a screenshot of my rules

I've tried setting gravity on the actor and on the scene, still can't get the jump height to any consistent behavior.

Bump, still don't have a fix for this.

The rules I use are slightly different... I don't have access to my computer right now, but from what I remember, I have the rules:

When spacebar is pressed (when game.jump is true) and When self.ontheground is true

Change attribute: Self.ontheground to false

Timer: for 0.18 seconds

When self.motionlinearvelocityY<200

Change attribute: Self.motionlinearvelocityY to 500 (or put whatever number you want here)

Let me know if this helps

EDIT: Also see this topic below, I posted all the rules I used for jumping which seemed to work pretty good, note that there are 2 other rules in there for detecting on the ground, and in the air

Could you not experiment with the interpolate behaviour?

I tried something and uploaded it here:

Check it out and see if that helps at all...

This worked perfect. Thanks for the help guys.

I have done extensive experiments with jumping. I really suggest playing around with interpolate, it seems to have the best results for me. Getting the jump to work right has been a big challenge. I do have a nice jump going, the hard part is getting it to behave well when you hit the side of a platform, that is where things get wonky for me.

I have found that when using interpolate, make the guy come down faster than they go up, that looks the most realistic.

Can you post an example of your interpolate rules?

Kind of a messy work around but my platforms are two make up of two actors. One will be the bottom and sides which the hero doesn't interact with outside of not. Allowing you to jump through. The second actor resides just on the top and that's the part he can jump off of.

could it have anything to do with Max Speed in the motions and then checking Apply Max Speed?
