graphic hotspot length + rotation

JGoode — Wed, 05 Dec 2018 11:15:32 GMT

I would like a graphic hotspot that can extend in one direction and also rotate around the base.

Is there any way that I can achieve this with one hotspot?

Thanks

I don't think this is possible - but if I am wrong please let me know.

You can stretch two lengths with what appears to be one hotspot by adding the x-length in the y stretchy hotspot and the y-length in the x stretchy hotspot.
The problem with an angle and length is you can add the length into the angle stretchy hotspot, but you can add the angle into the length stretchy hotspot.
At least that is the way I see it.

Wouldn't you just add a ROT before your length hotspot that references the rotation hotspot?

That is the problem.
The length hotspot can not reference the rotation.

Try this - works fine as two hotspots.
Create a 'length' and 'angle' parameter

HOTSPOT2 0,0, HSID
HSID=HSID+1 !increase ID for next hotspot

HOTSPOT2 0,0,HSID,angle,6 !centre !!512 flag for clockwise rotation
HSID=HSID+1 !increase ID for next hotspot
HOTSPOT2 (length-off_angle_hs),0,HSID,angle,4+128 !base
HSID=HSID+1 !increase ID for next hotspot
HOTSPOT2 (length*0.9)*COS(angle),(length*0.9)*SIN(angle),HSID,angle,5 !stretchy hotspot
HSID=HSID+1 !increase ID for next hotspot

ROT2 angle

HOTSPOT2 0,0, HSID, length,1+128 !base
HSID=HSID+1 !increase ID for next hotspot
HOTSPOT2 length,0, HSID, length,2 !stretchy hotspot
HSID=HSID+1 !increase ID for next hotspot
HOTSPOT2 -1,0, HSID, length,3 !reference
HSID=HSID+1 !increase ID for next hotspot

LINE2 0,0,length,0

Now change 'length*0.9' in the script to just 'length' or 'length *1.0'
You can still stretch the length but not the angle.
