How to check the duration in seconds of my actor colliding with a ground actor?

FirstDan

Hi all

When an actor jumps on a ground actor,
if the actor is on that ground actor for 3 seconds, i want to change the image of that background actor.

currently what i have is, when actor collides with ground,
timer- after 3 seconds
change attribute self.image to mychangedimage.png

but what happens is, if i touch the ground, it carries on after 3 seconds and changes the image..

How would i achieve this?

also why doesnt the following work

change attribute self.visible to false
but this doesnt work?

thanks

Hi @FirstDan, your first question about why it changes the image after 3 seconds.... because you asked it to. (Timer after 3 seconds). So I don't quite understand what you're after to achieve.

As for changing self.visible, you can't; this is one of those attributes that you choose its state before gameplay (like Moveable) which can't be changed with an attribute. Use change attribute self.Color.Alpha to 0 as a suggestion.

@gyroscope - thanks for your reply, here is what im trying to achieve, if my actor has stayed on a ground actor for 3 seonds, i want to change that image, but the actor must stay on the ground actor for 3 seconds for the image to change, hope that explains it better

thanks

Hi, do you mean 3 seconds exactly? The following should work:

When YourActor overlaps or collides with YourGroundActor
Timer After 3 seconds
Change Image

...but I get the idea you've tried that and it's not working?

Change 'after' to 'every'.

(use the up and down arrows to move the actor up and down - when he stays on the floor for 3 or more seconds he turns red)

make sure run to completion isnt checked. what gyro posted will work.

If you have run to completion checked, even if your not touching the ground for the full 3 seconds, 3 seconds after the first touch it will change, so make sure its not checked

Whoops! Yep, that's a much better way of doing it (and much less stupid than my way \m/ ) ignore my post !!

Leave your timer as an 'after' timer and make sure run to completion is unchecked.
