Also, it's got a great feeling, keen to see how this progresses!

@Tratax legend thank you il have a gander now cheers man

Tratax

@waldron All good! worth noting the camera movement speed also has the acc multiplier attached so that it can correctly match the speed of your skater

@Tratax great work man perfect, yes could go either way with this keep as is and keep flowing in one direction or fix the left to do the same as the right.
cheers man

btw your intros are fantastic to your games i still need to figure out how to load from intro to main game...

@waldron Thanks, the way I'm doing it still experimental and I'm not sure if its best practice but as everything is carried out sequentially, I try to take advantage of that.

Example:

// Call my intro/title function before the main game loop
// Once this breaks, it then moves into the main game loop

doIntro() 


// Main game loop
loop
     .. Main game code goes here 
     update()
repeat


// All my functions live at the bottom of the code
function doIntro()
loop
     clear()
     ..
     .. Do your fun title code here
     .. 
     c = controls( 0 )
     if c.a then
          break
     endif
     update()
repeat
return void

Update, more tricks, more level drawn and forward motion roll thanks to tratax!
Lots more moves/tricks to come.

I am impressed, reminds me of California Games. Also it was a BMX discipline there. It looks like this will be as fun as well.

This is looking AWESOME. Keep up the good work!

so im at the point where im updating this whole game with every thing iv learnt so far anything i learn after i will make a 2nd game in the series but for this one im wanting to add 2 other elements im not sure on how to implement..

1.entering end of level - to level 2, entering house/shop screen
kind of know how to do it but is there a better way?

House()
Endlevel1()
Shop()
thinking of creating an item that il mask in the screen so... black door way with black item
collect = said item then house.

2.slopes collision edge detection so player can move diagonally on a 2d game

You don't necessarily need to create an item to collect to go to the house. You cold simply add a door sprite and check if the player collided with the door. Then you know you'll need to load / display your house.

@waldron I just implemented board switching in my game last night! What I did was define each board in an array, with a sub-array containing all of the sprite definitions for that level. By "definitions", I mean the X and Y coordinates of each sprite, the type (such as "teleporter"), and (for teleporters) the destination board and X-Y coordinates, for when the player touches the teleporter.

I have a function called "switchMap()", which grabs the appropriate board element, loops through the definitions for that stage, and populates the level. It does this by creating and adding sprites to an "actors" array, mapping over the properties from the definition to the sprite (so the teleporter sprite will have properties like "targetX", "targetY", "targetBoard", etc.).

This all makes my "draw()" function trivial; it just loops through the "actors" array and draws each sprite according to the properties. Adding a new element to a board takes like ten seconds: just copy and paste an array entry in the board's "definitions" sub-array. Done!

In my main game loop where I'm checking for sprite collisions, if the 'currentSprite.type == "teleporter"', I call my "switchMap()" function, which unloads the current map, loads the "sprite.targetBoard" one, resets the player's X and Y coordinates to "sprite.targetX / sprite.targetY", and boom-- the player is now on the new map, in the correct spot.

I even have "switchMap()" switch the background music to the correct song, which I have in a property in my "boards" array. I have a working transition between a city "overworld" and a sewer "dungeon", and it was really gratifying the first time I could leap between the two at will.

Hope that helps at least somewhat!

waldron

@Spacemario wow thankyou so much for the detailed comment great help thanks

Spacemario

@waldron Sure thing! Let me know if you run into any questions.

Incidentally, I'll be working on my game tonight-- I found a bug yesterday, where I am accidentally doing an operation on an unloaded sprite in my "actors" array (crash!), but only after switching boards 3-4 times. I'm sure it's a simple bug in my logic, but it's odd that I need to switch boards multiple times for it to manifest. Weird!

waldron

@Spacemario cheers im reanimating my character atm but might start laying down framework for the level switches sure il be needing your help again haha thanks man

Spacemario

@waldron I fixed my weird bug a couple of hours ago! I had code something like this:

for i = 0 to len(actors) loop
    curSprite = actors[i].sprite

    removeSprite(curSprite)
    ….
repeat

For some reason, that "curSprite" variable was referencing a sprite other than "actors[I].sprite", because the crash error was telling me, "you can't remove a sprite which has already been removed, you dolt!"

So, I replaced all references in my loop to "curSprite" with "actors[i].sprite", and the code worked.

Next step: the HUD.

@Spacemario glad you got it working man,
I'm trying to get y axis movement atm but character vibrating on the collision map lol

@Spacemario Want to be able to move up and down y axis but hitting collide map. Want it like the simpsons game style.
Ignore background still building the level. alt text
