Collide / overlap rule not working when using change size

Strobanik

well, the title says it all. suddenly all the rules that responded to collide / overlap in an actor stopped to work. after removing the "change size" behaviour they worked again.

RH

That's because the collision size/area doesn't change. It stays the same as the original size of the actor.

What you need to do is destroy the first actor and spawn a bigger version in it's place

POM

what i would do is check the size of the actor when it reaches collision and make a rule in it
when height/weight >= the size of the collision
change attribute "game.collision is on" to true
otherwise - false.

and in the other actor say that
when "game.collision is on" = true
do something

or if you want it to dont do something - so add to the rule you dont want to apply:
when ALL are valid:
"game.collision is on" = false
and all the other rules

hope it helps!

it's a bug. p-o-m's work around looks reasonable.

hey, thanks for the inputs. pom's workaround would have worked, if not the actor wasn't always in different sizes when colliding. The strange thing is that the change size behaviour just had to be in the actor (inside a rule that is not active) and still f.u. the collide rule. but it's good to know that it's a bug and not something fixable. I used a timer that increases the width and height instead, seems to work now.

big cheers

rebump

Use "change attribute" for "self.size.width" and "height" (possibly inside a timer if you want them appear to grow or shrink) and the collision works with the newer sizes. It is "change size" that is broken.

I can't believe after 1 year this bug hasn't been fixed yet !!!

This is really a bad, I developed a game using "Change Size" behaviour, and it was running at 60 frames per second, now in some occasions goes down to 5 frames per second, and gets all shaky, and pauses all the time. could this bug be fixed?
