Jumping and Side Collisions

TommyTank

I have created an actor and jumping works fine when my actor is on top of a solid. If, however, my actor collides with a solid whilst mid jump, my actor lands and the jump button no longer functions. Is there a way to get my actor to jump again after a mid air collision with a non-moving actor?

My jump is set up like this:

I have added an integer attribute 'Jumps' set to '0'

Actor receives event - key - space
Attribute - self.jump > 0
Change attribute - Self.Motion.Linear Velocity.Y to 400
Change attribute - Self.Jumps 0

Actor receives event - overlaps or collides with - actor of type - solid
change attribute - self jumps - 1

Thanks

Is there a way to get my actor to jump again after a mid air collision with a non-moving actor?

I added wall jumping to Arch Fiery... http://photics.com/arch-fiery/ ...which seems similar to what you're trying to achieve. I found that I could have greater control over jumping (more consistency too) if I constrained three invisible actors around the main actor... to the left, right and bottom of the actor. So if the right sensor actor was overlapping a wall, then a wall-jump is possible.

That's helpful for wall jumping but the actual problem I am encountering is:

Once my actor hits the wall mid-jump and falls down to the floor, even after moving backwards and forwards along the floor platform, when I press the space bar (the jump button) nothing happens.

It's probably just a typo but in your post you mention self.jump AND self.jumps, are you mixing your attributes up in your behaviors?

I'm thinking it might be a typo too...
...or maybe the logic could be changed.

Why greater than 0?
Shouldn't it be less than 2?

I'd probably use a floor sensor.

If floor sensor overlaps or collides with actor tagged (Floor)
Set Jump to 0

If space is pressed and Jump is < 2
change Jump to jump+1
change linear velocity to +400

I'm kinda sleepy, so my logic might not be right, but I'm thinking that's the approach I'd try for wall jumping.

TommyTank

yeah the 'self.jump' was a typo. sorry guys.

I'll have a play around with what you suggested later and report back.

Thanks for taking the time to answer my question.

I'm still hitting a few problems. I'm gonna keep playing around with my logic and see if I can resolve it (I've only been using GS for 2 days so I think I just need to spend a bit more time experimenting.) Your comments were helpful though.

What I've ended up doing through a bit of trial and error which seems to work for now is to create a timer - every 0 seconds and uncheck run to completion and put all of my jump behaviours inside there. I think that is resetting all of the attributes that were stopping the actor from being able to jump again.
