view movement...

[friedfish]

What are you guys using to move your view actor? I'm looking for a way to move the view smoothly when you go up and down.

Currently I'm using canvas actors to move the view up, down, left and right.

What are yours?

I'm always a bit mystified why people use canvas actors to do this. But, I constantly see it. canvas actors are meant to be drawn on via canvas functions. If you want a collide able region you should use a filled region, or in some cases a wireframe. Anyway, I usually use two lines of code.
player -> Draw Actor -> Script Editor

Code: Select all

view.x = max(x-view.width/2-200, min(x-view.width/2+200, view.x));
view.y = max(y-view.height/2-150, min(y-view.height/2+150, view.y));

Though usually the player is parented to a colliding region.

ah sorry my mistake... I am using a wireframe... my fault.. your two lines of code is good but it gives me problems...
for example if I parent the player to another actor it disappears and show me beginning position of the view.

I have a moving platform which when the player rides it I parent the player to it so it follows... it was okay when I was using wireframe, a little screen shake because when the player collides to the wireframe while riding the platform it shakes the screen.

when I used the codes you have and when the parent changes the view seems to go back to its beginning position... your code was much smoother than the wireframe method. I like it. Is there anyway you know I can fix the view change problem?

As I said, it isn't the same if you want to handle parenting. In that case you should use xscreen/yscreen variables, as they aren't influenced by parenting. The only difference is you need to change any x/y variable references for the event actor to their equivalent xscreen/yscreen (x = view.x+xscreen).
