Hey there,
I need some help with Isometric and i hope someone here can help

Here is my Problem:

I want to draw Walls in the Room.
Every tile get Calculated this way:

worldX = (isox * (tileWidth / 2)) - (isoy * (tileWidth / 2));
worldY = (isox * (tileHeight / 2)) + (isoy * (tileHeight / 2));

worldX = worldX + (tileWidth / 2);
worldY = worldY + (tileHeight / 2);

The Walls i calculate this Way:

worldX = (isox * (tileWidth / 2)) - (isoy * (tileWidth / 2));
worldY = (isox * (tileHeight / 2)) + (isoy * (tileHeight / 2));

worldX = worldX + (wallWidth / 2);
worldY = worldY - (wallHeight / 2);

Some more Informations:
tileWidth = 54 - 2;
tileHeight = 33 - 1;

wallWidth = 32 - 1;
wallHeight = Dunno atm, not @ home!

Hope someone can help me!

What exactly is the problem you're having? Are the walls not lining up properly?

The Wall Coordinates get calculated wrong,

They go down. Every new ISOWall Instance the Walls are 2-5 Pixels to much down.

Are you applying an offset?

Oh yeah, sorry i forgot!

OffsetX = 200
OffsetY = 100

Since you are calculating the placement from the tile height and width the height should ALWAYS be half of height. Change the height to 26 and see how it does

I think 26 is a bit to low for WallHeight...
I'll test it later, if anyone has other Solutions: Simply Post, i'm happy for every help

It's tile height you need to change to 26. Think about it. In isometrics you move 2 across and then 1 down, this means width should always be twice the height when calculating positions. Since you use tile height to calculate positioning then it needs to be half of the width.

If you don't want to change the tile height you could always do this:
worldY = (isox * ((tileHeight - 6) / 2)) + (isoy * ((tileHeight - 6) / 2));

Thank you very much, Assassin

You solved my Problem, walls now get displayed right!
