now I need three more things before my code is complete;
1) The speed boost to add speed that goes away in 5 seconds to Bob when he comes near, causing the speed boost to respawn and the score to go up one.
2) When the shark comes near, I want it to display "game over" and the recently earned score as well as the best score scored on the console.
3) I also need to use the blitting tool to make the image I created for the speed block have a strobe effect.

... Um how do you link a picture?

Oh yeah, instead of the shark being controlled, I need him to always be traveling in the direction of Bob

Are you using flash or flashDevelop?

Yes indeed.

Hey no problem...

Is your img in a folder? Or is it there with your program files?

Oh I mean to this website not to flash

:O

I don't know what you mean.

how do you put a picture on armorgames?

one way, is to take your img and upload it to a hosting site. imgur is a good site to use, among the many.

Once your img is uploaded to the img hosting site, you then take the link that is associated with the img and paste it here using the img button.

k thanks. Now will you help me make the speed boost actually boost the speed?

you will need to create a variable containing the speed I am assuming you will want it be speed boost for a short amount of time then you will need to create another variable which will be the duration of the speed and after it counts down the speed will be back to normal.

in your loop it will be changed as so

then when in your collision add

in your loop

var speed:int = 10;
var speedDuration:int = 30;

Okay, now how do I add in the collision, I've done
[quote]var speed:int = 10;
var speedDuration:int = 30;

in your loop it will be changed as so

char.x -= speed;[quote]

If you haven't added the collision then changing the speed is irrelevant.

You can take a look at part 3 of my tutorial at the very bottom is the collision. if it is too confusing then you can try googling as3 hitTestObject or read up on adobe's display object on the method. Once you get the collision to register then you can add whatever it is that you are trying to achieve, in this case it is speed boost.
