adjusting image to collision box

[keneda83]

Hello guys i'm trying to make my own picture for a building but i'm having pain to adjust the pics to the collision box does anyone can explain how the picture is loaded and how it work with the collision box? thanks in advance for any help!

There's three settings - collision_box (footprint of the entity on the ground), drawing_box (actual size of the entity) and selection_box (where the selector lines will be drawn if player hovers/clicks entity).

Each has an area object - { {left,top}, {right,bottom} } where those values are offsets from the centre of your object (as far as I can tell). A map tile is 32px square, so a value of 1 will represent 1 tile. If your entity is 1x1 footprint, then the collision box would be something like { {-0.5,-0.5}, {0.5, 0.5} } (I think?!)

In game, if you press F4 you get a debug panel appearing - there are two options that will help:



It draws the actual boxes so you can see exactly where they are:

So, basicly i want to adjust the bottom left right of my building with the collision/selection box and allow the picture to be fully displayed, i tried to play with the drawing box but no luck.

First off: Your sprite is way bigger than your collisionbox, so you should adjust that via collision_box and selection_box, the collision_box should be a tad smaller than the selection_box.

If you want to move the sprite relative to the collision_box you need to use the shift value specified with the sprite.

ok thanks you very much for these info i will try to play with those shift option (how does it work exactly? , it just have X and Y right? and it appliy from the center of the entity?) and probably reqize my picture

the game renders from left to right and from top to bottom, so the y axis is inverted (+ down, - up)
