[AS3] walls and sprites

[blue969]

I haven't coded much in actionscript yet, but anyway, I was wondering about coding walls and sprites.

Walls-how would you make it so that if a character hits a wall, it can't go through it. Would you multiply the walls width and heigth by each other and tell it that it couldn't go inside the boundaries of it or what?

Sprites-If you want it so that a character will have a different appearance when walking left and a different one when walking right or shooting or jumping, how would you do this?

Look up hitTestObject and hitTestPoint. These will tell you if two objects are touching, and you can adjust their speed and/or position accordingly.

There are alot of ways to do it, but one common with is to make each frame in the timeline a different sprite. For example, frame one could be standing and frame two could be jumping. If the character jumps, call gotoAndStop(2), when they land, call gotoAndStop(1).

I don't know if what I heard was true, but I heard that that could only be done in as2?

I'm very sure it can be done in AS3. Where did you hear that it couldn't?

I forgot the exact name of the website, but it was some tutorial website.

Maybe they meant the commands were different or something. You still have a timeline in AS3, and you can still stop it on certain frames.

Also, another question I have is how would I make a flash game have multiple levels/stages in it?(I have some Ideas but I think there is probably better and easier ways than the idea I have)

[Impacatus]

I would just make each level a different movieclip.

If you want to make a level editor though, you'd need to write some kind of algorithm to generate the level based on data you provide.

I actually thought of the movieclip Idea before, but then I noticed that if you press ENTER on the flash player you can start or stop the movie, so doesn't that mean you can skip a level if you press enter?

I assume you mean in the flash testing environment. I don't think you can affects swfs you play in your browser that way.

Also, you're probably thinking of frames, not MovieClips.
