How would some of you guys go about this?
Because I've been trying to make them for days.

I suppose it's just a problem of keeping things out on only one side;

[Noisefever]

the way I have chosen:

store the last position of your player (always). if the player collide with a jumpthrou block, then check if he collided at the last position.

collided: continue falling
not collided: check player direction. if downwards, then he have stop on the block (move him out upwards). any other direction but NOT down: continue falling.

I hope I remember that correctly.

Yeah it's all about checking the previous position against current position (or current position against next position depending how the collision works).

Or another way to look at it is, if the player is moving down, the height of the platform's collision = the player's Y movement per frame.

[Ben_Hurr]

Ah, but what if you stack those jump through tiles on top of one another?
Then by how you folks are doing it, if the player overlaps another jump-through tile with any other part itself, it'll fall through the tile it's standing on right? :V

[Noisefever]

not if you check tile for tile (on a tile based map of course). i don't know how you check your collisions, but looking only for a collision "group" is generally a bad idea i think. if you have only pixel based collisions this will not work. and i don't know a way to do this with only pixel collisions.

As long as you don't move the player before checking for collisions, you can just test collisions only on tiles who are below the player.

That is, you only check a tile "Tile" for collision when Tile.Top <= Player.Bottom, except using variables that actually exist (unless you're using Visual Basic :3).

[Ishi]

In the past I've moved the player, then checked whatever tile their feet are overlapping. As long as the player isn't moving more than one tile per frame it's fine.

[Ben_Hurr]

Thankfully I already figured out how to do it on my own. :3c
But thank you for the help anyway.

God I should really post this thing in DevLogs or the feedback board.
