Well, I never knew that I want to know these random facts.
But it's awesome, thanks for this tutorial!))
I linked this in the Link List, added headline in your post and also highlighted timakro's answer in your first post .__.

28x28

29x29



If a tee is 28x28, it should be able to move 5 pixels in between 2 blocks?

but if its 29x29 , its able to be in 4 places, it would make sense to what im corneum found out about.

So how big is a tee really? is it 28x28, 29x29 or something else?

Really interesting question.

<3 to topic starter.

Character size is 28

Code: Select all

int CCollision::GetPureMapIndex(float x, float y)
{
	int Nx = clamp(round_to_int(x)/32, 0, m_Width-1);
	int Ny = clamp(round_to_int(y)/32, 0, m_Height-1);
	...
}

Tile size is 32


32-28=4

32-28=4 but the 4 should be the pixels the tee can move then. How does he only move 3 pixels in the video?
Something went wrong there.

Cloudly i move only 3 pixels because i am already standing in the first position, the ground/wall.

Aoe is right, would be interesting to know whats true ^^

so there are 3 things we have to be aware of:
1. the stoppers could have a bigger Area-of-effect (Aoe ;D) than one block
2. the hook-unhooks could be smaller than one block
3. teesize is hard to find out because we dont know what tile is 1 block big, also tees are wobbly. :D

Your right, the real size of a tee is 29x29! This piece of code is used for collision detection, in vanilla also for the flag for example, it gets passed 28x28 as tee size but makes the object 1 bigger than we would intuitively expect. https://github.com/ddnet/ddnet/blob/609 ... #L329-L385

That is literally what i said.
you can move 3 pixels.. but with a tee being 28x28 you should be able to move 4 pixels.
