Water on top of player

[Fyll]

David, could you make the water tile see through? I think it would look better if we did that, then drew the water ontop of the player instead of the other way around. It'd have the added advantage that when a block falls on your head, you will disappear behind it, rather than staying in front like you do at the moment.

I can do that fairly easily, yes. It will only work if we're using z-transparency though, rather than alpha-testing. I'm not sure how we're set up at the moment.

(to clarify, if we're multiplying by alpha, it should work, but if we're just checking alpha is above a certain threshold, it'll either go fully transparent or not transparent at all)

[Fyll]

... I'm not sure I understand. I meant actually changing the art to be transparent. Then, as long as the guy is drawn before the world (which he isn't at the moment), he should be behind it.

[DivFord]

Yes, I got that. But the shader code will determine how that actually shows up in-game. You know what, I'll change the spritesheet, then see if it works or not.

[DivFord]

Ok, tile set is changed and works fine. As an aside, you seem to have removed jump leeway. Did you mean to? Some of the rooms are unwinnable now.

[Fyll]

I changed the way jumping worked, and jump leeway seemed to stop doing anything, so I removed it. Are you sure they're unwinnable? I haven't bumped into any unwinnable levels since making the change.

[DivFord]

Lv8. Jump leeway should still have worked - all it changed was the times jump could be called, not the implementation. It was quite subtle, so may not have been noticeable.

[Fyll]

Huh. I'm pretty sure I've managed level 8 without jump leeway. Having just tried again, I can say with certainty that Lv. 8 is completable (the one where you come in and leave on the left, and there are two floating and one sinking blocks).

[DivFord]

It's still doable, it just doesn't feel nice. The jump is really tricky to pull off from the tiny platform.

[Fyll]

So, what did jump leeway do that made jumping from a single tile easier?

[DivFord]

It had a timer set to 5 while you were on the ground, which it ticked down each frame you were off the ground. There was bool called didJump that got set to false when you jumped, and true when the timer ran out. So for five frames after leaving the ground, you could still jump, so long as you hadn't already. That way if your reactions are slightly too slow (due to input lag) you still manage to make the jump. It's fairly standard in platformer control schemes.

Aah. I see. I'll stick it back in then.

[Fyll]

All done.

[DivFord]

I added didJump back in, and I set jumping back to a velocity change. It felt really weird accelerating upwards. A jump should be a sudden force as you push of the ground, unless you have rocket thrusters.
