I need some advices regarding collisions.

So, Hi there

I'm having some troubles with collisions,

I'm making a platformer game, with semi-randomly generated worlds,

I said semi, because it just randomly picks premade structures, not make them from scratch.

So for example,

let's say some of the premade structures I have is this:

That is just a .png image.

I could just edit the collision box, but I would need 12+ collision points,

and at that point the engine starts telling me that's a bad idea..

Even more considering I use 10 or 20 of those on a stage.

How could I set the collisions better/properly?

You could just use invisible dummy sprites.

I thought that,

but as I said I'm not making the levels, they are generated randomly,

how would I know where to put them?

Ahhh. I should really be more careful when reading a post Totally missed the randomly generated part.

The only other idea that comes to mind is to build your structures from smaller geometric primitives. That way, they can all have a default collision mask, and you can attach them based on (multiple) image point location.

If you break your collision objects down into basic shapes such as triangles or squares and make them invisible you could run a script at the beginning of the layout to pin each collision area to the correct shape (sorry bout the pseudo script but something like)

On Start of Layout - Triangle_Object - spawn Triangle_Collision on layer 0 (image point 0)

For each Triangle

I don't know if it would be more or less efficient than other methods though as I guess you'd essentially be doubling your objects.
