I might be miss understanding the question you are asking, but the below tutorial helped me with random generating power ups. I hope this helps :)

Tutorial

Question 1 and 2

1.)On the layout menu, right click away from any graphics.

2.) Look on the left side menu, it should say layout by default. If you look through it, you will find the height and width.

I did this in order to get my game to load in the arcade.

As for question 3_ Check this guy out, he really helped me...

Sadly this may be a ludei twitter question because they don't have any real forum support. Also here's a link to the forum post here on C2 scirra.com/forum/cocoonjs-launcher-app_topic54277.html

Best help I can do, didn't want to leave you hanging. On this forum

I'm very interested in how you are going to integrate Unity, because another game maker said he had huge problem porting code. I take it C2 runs on JavaScript and I know you can use JavaScript in Unity. Can you share anything about your planed process?

I see, but I'm trying to time out the ability the player gets from the power up.

Here's a better question, how do create a random word generator?

Thanks all,

blackhornet, How do I use the timer, I can add the timer, but how do I set the power up to stop working?

— "PowerupTimer" is an "instantance varible"?

MustacheGolem, thanks man, but the file url doesn't work.

How do I time-out power ups?

Ok, so now I have a super awesome super speed power up, but I only want it to last 3 seconds. I tried to do varibles on "system" and on "player" but the game doesn't seem to register either.

Any suggestions?

Hey are you pinning the armor onto the character. If so, have to consider a Ghouls and Goblins aproach to armor damage?

As an educator with 6 years of teaching from grade school to college, I see more faults than benefits to go to college and go into debt. Moreover, the fact that most programs do not teach basic coding really bothers me. Thus, I am glad I was given a chance to teach 6 students who wanted to learn how to make a video game the basics of how the internet works, and how Construct 2 works. However, I don't feel and contend with many experts that you need to go to college to get a good job with all these forms of alternative education and funding from projects to research. Colleges in themselves are awesome and help make the world a better place by creating research and developing projects that are not just centered on making money, but too often too many people are going to school when they don't really need too because they think they have to. Just my opinion.

Thanks that worked perfectly, now just to figure how to time out the power up.

How do I increase or decrease a players movment with a "power up" item?

So in my game coding, I realize if I set the max speed to 3000 in the left window under beaviors: 8Direction: I can create a power a sprite that when on colision can make the character go 3000.

However, I don't want the player to acclerate to 3000 at the strat of the layer. I want the power up to give them that ability.

Also, how do I set a timer, so that the power-up will stop working?
