Sprite bounding box

[prvi_treti]

Hello there,

 

  I just finished MVA course (thanks to English subtitles (jk)) and hope my question makes some sense As I consider an isometric game involving map, I need something like,

 

 

as in Dao Chemicals building of Simcity 4. When I asked Ocean Quigley about it, he briefly said that "We UV'd the building sprites onto those boxes" . But considering that I will use prerendered assets ie sprite, I wonder if it is wiser and/or possible to use a bounding box for sprite , something like

 

 

And considering that I also need to highlight sprite when mouse is over like

 

 

So my question is, should I go with UVing simple geometry or use sprite with bounding box? And In case of latter (which I favor), does it lead to any issue I can't foresee atm?

 

Thanks in advance,

Hey, thank you for my english accent

 

I would rather go with UVing simple geometry because you will have more control over positioning, collisions and special effects

Thanks for reply.

 

Beside the fact that I still didn't fully get how to UV simple geometry because at all examples they UV a crate , wouldn't it be a problem to highlight "texture" when mouse is over box but not over texture itself?

Do you want to highlight only when mouse is over the texture right?

Sorry for late reply.

 

Indeed, I want to highlight texture/sprite only when mouse is over/down. In addition to this, for future collision detection I need a bounding box(/mesh/simple geometry ? not sure how to call it) as well.

Bounding boxes/bounding spheres collisions are provided out of the box

For texture picking, you can use scene.pick and then use the pickingResult object to get the UV of the picked point

Sorry for late reply, pity didn't have chance to try your suggestion yet but will be pleased if you can clarify whether (for example),

 

 

container next to building (outlined in red) can be picked this way or not.

 

Thanks in advance.

Is it an object in this case? or is it part of the big box?

Indeed, it's a separate object.

so no problem
