Platforming and Collision Code

[Connors]

Guys I think I can add scrolling without a total rewrite of the sprite code for the game! I'll keep you posted.
EDIT: There are so many problems with this idea that I don't really wanna mess with it tonight.

Usually adding scrolling only requires changing your drawing code to have a moveable "camera" that can follow the player.

Scrolling'd be cool.

[Connors]

I kept the original code, which is fine, yet when I set "LET scroll = true" the map moves and the player acts as if his xpos variable is static.

[Gan]

Fixed it for ya.

[Connors]

Alright, this is fantastic! Now I can make big ol' levels where you have to make wall jumps and change direction in mid-air other such physics-defying nonsense.

May I ask what you did, and how I can constrain scrolling to the x or y axis if I want?

[Gan]

Your code was right on for the most part.
I just made two variables:

Code: [Select]

LET cameraX = xpos(player) - 500
LET cameraY = ypos(player) - 300
MOVESPRITE object, x - cameraX, y - cameraY

This is the magic code that makes the universe revolve around the player. You can constrain with if statements:

Code: [Select]

IF cameraX > 500 THEN cameraX = 500

[Connors]

Right. Great. And I can easily turn it on and off!

Now I need to remake the variable size editor. I could have sworn I already did this once before, though...
