Ok, so I’m making a overhead game and I want to make the terrain movable. But the only problem, I have objects which the player hitTest on it. So how do I make everything scrollable? ---

have everything in 1 mc, like terrainMC. and then do hitttests from there, ex; char.hitTest(terrainMC.block) understand ? ---

Aw, curses I was afraid you would say that. Ok, so I just put everything under one MC. So now I just do, if(Key.isDown(Key.RIGHT/LEFT)) { \_root.terrain\_mc.\_x -= speed } So what if the player moves to the edge of the map? ---

depends on how you built it / reg points, etc… attach your fla and i will tell you on how to make it ---

doesnt combining the mc’s into one movie clip always make the hitTest equal true for all it does is wrap a rectangle around the mc and check if the rectangle and the object are touching. correct me if im wrong but i had a problem when i made a game because i put the 4 walls into one mc and the hitTest always was true. ---

okey i looked at this. this is the worst kind of progamming 🙂 were you have all code in the movieclips… i could never navigate thru this… What you need to do is: [AS] //EX block the char from walking left ( becouse the map ends there): if(char.\_x\<0){ //cannot walk this way } //EX block the char from walking right( becouse the map ends there): if(char.\_x \> Stage.width){ //cannot walk this way } //EX block the char from walking up( becouse the map ends there): if(char.\_y \<0){ //cannot walkthis way } //EX block the char from walking down( becouse the map ends there): if(char.\_y \> Stage.width){ //cannot walk this way } [/AS] As you se you cannot use the code straight ahead… you need to have these each respective movement statements, LIKE if(){}else{ here you change the X and Y ) GOt it? ---

um…kinda heres my current code: (I placed everything under one mc called “terrain”) ```auto onClipEvent (load) { movespeed = 5; } onClipEvent (enterFrame) { if (Key.isDown(Key.RIGHT)) { _root.terrain._x -= movespeed play(); _rotation = 90; _x += movespeed; } if (Key.isDown(Key.LEFT)) { _root.terrain._x += movespeed play(); _rotation = 270; _x -= movespeed; } if (Key.isDown(Key.UP)) { _root.terrain._y += movespeed play(); _rotation = 0; _y -= movespeed; } if (Key.isDown(Key.DOWN)) { _root.terrain._y -= movespeed play(); _rotation = 180; _y += movespeed; } if (Key.isDown(Key.RIGHT) && Key.isDown(Key.UP)) { _rotation = 45; } if (Key.isDown(Key.LEFT) && Key.isDown(Key.UP)) { _rotation = 315; } if (Key.isDown(Key.RIGHT) && Key.isDown(Key.DOWN)) { _rotation = 135; } if (Key.isDown(Key.LEFT) && Key.isDown(Key.DOWN)) { _rotation = 225; } } ``` Now, I have no idea how to stop the terrain mc from moving onces it hits a certain x/y point of the stage. I tried if(\_root.terrain.\_x \< 0)) { the terrain moves, but it still doesn’t work. Also, when the player is being blocked by a wall and cannot move, the background keeps moving because the key is still down. How do I change that? ---

is that under terrain mc and not under player mc? have you uploaded an older verison? ---

Don’t mind the .fla file I haven’t update that yet. I put that code on “player” mc. If I put it on terrain mc, once it hits the edge, the player will be unable to move. ---

wait wait wait… no im confused. becouse i came to think about some stuff that you need to add… have you made it working? ---

yes the terrain is scrolling now, but my problem is, I don’t know how to set boundaries for the terrain. And also, when my player is being blocked by a wall, the terrain keeps moving while my player doens’t move. Heres the swf file: \*\*[http://spamtheweb.com/ul/upload/180508/69378\_kindemo.php](http://spamtheweb.com/ul/upload/180508/69378_kindemo.php) \*\*As you can see, if you try to go through the guard, the player doesn’t move but the terrain background keeps on moving because the key is still down. ---

im sorry. but this project has so much stuff i cant deal with… rewrite the code to Frame 1, and place all objects with AS. use listerners instead with Switch for moving, instead of OnEnterFrame with If… Then i will help you 🙂 ---

wish I can, I’m off to a messy start am I? I don’t know how to code listeners yet, heard of them though. And you mean to put the code that moves the player/terrain on the frame? Can you give me any good links to tutorials for listeners? ---

I don’t know how to dynamically place the objects on screen, I have don’t know what are listeners and “Switch”, and what you mean by rewrite all the code to Frame 1? Can anyone explain? ---

with rewrite, i mean to rewrite all the code so you can use it from frame1 instead of having it everywhere. i useally charge 100usd / hour doing this 🙂 but i will come up with some guids for you. hold on! ---

Switch: [http://www.kirupa.com/developer/acti...switchcase.htm](http://www.kirupa.com/developer/acti...switchcase.htm) Key listner: Check F1-help for Key.getCode and the example they have will bring up listner. allso check AttachMovie() in F1-help for attaching MCs to the stage. Be sure to read everything becouse there is a part about linkage. Without this you cant chance ‘map’ or ‘level’ . ---

Ok, I don’t mean to bump a old thread, but I really need to know how to stop a scolling terrain from moving. If you look at my other posts, you’ll see the .fla and the codings. Any help would be appreciated.
