Stop actor falling over

thelogobar

Been searching for an answer, but it's tricky finding things on the forum.

I'm fiddling with a game idea and wanted someone on a skateboard or similar, just skating and using ramps at the moment. So far so good, but the actor keeps falling onto its side. I want the actor to be able to rotate on ramps and in the air, but not so far that it falls over completely.

Can I constrain the rotation angle? Or make the actor right itself when on its side?

You can use the "Constrain Attribute". Constrain the Skateboard.Angle to 90 degrees.

You can also say:

If
{ Skateboard. Angle > 10 degrees }

Do {
After 3 seconds {
Change Attribute "Skateboard.Position.Y" to "Skateboard.Position.Y+25"
-- Move up so it can correctly adjust angle --
Change Attribute "Skateboard.Angle" to "0"

-- You can also add this: --
Change Attribute "Game.Lives" to "Game.Lives-1"

what @lukey5227 said:
in GS language …
Rule: when
Attribute: self.Rotation > 10
--Timer behavior
[After: 3 seconds
--changeAttribute: self.Position.Y To: self.Position.Y+25
--changeAttribute: self.Rotation To: 0 ]
===

suggestion:

gameAttribute …angle type … name: rampAngle

on your rampActor (prototype)
add an attribute: angle type … name: myAngle
Rule: when
Event: overlaps/collides with Player
--changeAttribute: game.rampAngle To: self.myAngle

on instance of rampActor in scene
set myAngle to 10 or -10 … 10 for leanLeft … -10 for leanRight

on your playerActor
Rule: when
Event: overlaps/collides with ramp
--Timer behavior
[Ater: 0.1 seconds … this gives time for the value to be changed by ramp
--changeAttribute: self.Rotation To: game.rampAngle ]
Otherwise:
--changeAttribute: self.Rotation To: 0

Aha, so I have done this...

If self motion linear velocity X = 0
Interpolate attribute to 0
Duration 1 sec ease in.

This way if it stops upside down, then it self rights. Does the job.

That looks a touch over my head, but I'll give it a go.
Constraining the angle to 90 degrees, won't that stop it rotating at all?
