  • I'm trying to tell whether a sprite is colliding with another sprite from the top, left, right or bottom. I thought I could it with a combination of the angle of movement and the size/position of the sprites (assuming they don't rotate).

    It's a fairly involved calculation, so before I went too far down that route, is there a simple built in thing that can tell me the position where on a sprite a collision occurred?

    Failing that, is there a way to get the angle of motion from a sprite immediately before a collision? Getting it on the collision returns 0 (which is technically correct and useless in this context).

  • Why, why, why is the Sprite.Angle between 0 & 360 but the 8Direction.MovingAngle between 180 and -180?

  • Can I use Jump-thru as a one-way door? such that I can fall through it, but not jump up it?

  • Am I using it wrong? I'd have thought that these wouldn't collide because they have different tags:

  • Found it! It's hidden away in the Misc section. Of course.

  • Cheers dop2000,

    Where is that filter?

  • Can I make a sets of sprites have different solid behavior for different sprites?

    e.g.

    Sprite A is solid to Sprite B.

    Sprite C is solid to Sprite D.

    And maybe some sprites are solid to some only if some instance variable is set.

  • Is there a function to pad a string?

  • Maybe console.table could help: 

    var foo = [[1,2],[3,4],[5,6]];

console.log(foo);
console.log(JSON.stringify(foo));
console.table(foo);

var bar = [[[1,2],[3,4]],[[5,6],[7,8]],[[9,10],[11,12]]];

console.log(bar);
console.log(JSON.stringify(bar));
console.table(bar);

  • I'm assuming that behind the scenes the array is a JavaScript array? In which case it a multidimensional array is basically an array of arrays of arrays.

    (Don't understand why C3 has this odd array object with just three dimensions though)

    How worried should I be about these? Is there any way I can estimate what problems they might cause?
