pick.entity

[Dozz]

Well, I am getting on well with my cpp testing, achieving results in hours whereas I was expecting a big learning curve. Leadwerks & this forum = great.

Using CameraPick, I am selecting and highlighting objects no problem, and displaying pick.X etc..

 

I have defined:

float distanceto = 0.0;

 

and inside the main loop:

DrawText(10,70,"distance: %f",distanceto);

 

after the CameraPick:

distanceto = EntityDistance(cam,pick.entity);

 

...this does give the distance to the selected object ok, but to its pivot point. I want the distance to the exact picked point on the object given in pick.X, .Y & .Z

What is the proper way to do that? I know its not to work out the trig manually between x,y & z points.

 

Thanks for your help

I know its not to work out the trig manually between x,y & z points.

Well thats exactly how I do it! I wrote a small function that takes two vec3s for the positions and uses pythagoras to work out the distance returning the float.

 

Failing that, you could temporarily position a pivot entity at that position and use that in the EntityDistance function.

dx = pick.position.x - camera.position.x

dy = pick.position.y - camera.position.y

dz = pick.position.z - camera.position.z

d = sqrt(dx*dx+dy*dy+dz*dz)

I had this in class last week. Only in 2d instead of 3d.

Mathlib has already a Length() function which does that, it's automatically available when you #include "engine.h".
