pivot angle

[cassius]

Hi

How do I find the angle of a pivot so I can express it in UpdateController?

 

In the code below I get the error "can't convert from tvec3 to float" in updatecontroller angle parameter ( Blitzmax)

I need the controller to move in direction of player

 

 

pointEntity(bg_pivot,player)

PointEntity(badguy,player)

 

If stopanim2 = False

If EntityDistance(jane,badguy) > 2.0 And EntityDistance(jane,badguy) < 16

turn = EntityRotation(bg_pivot,1)

bg_framebegin = 77

bg_frameend = 115

animate_badguy() ' badguy walk

UpdateController(bg_control,turn,3.0,0, 0, 1,400,0)

Endif

 

EndIf

As the error says Cass, "can't convert from tvec3 to float" ... turn is a Vec3 but the UpdateController wants a float, so try turn.y which is the y value of the Vec3

Thanks mg. I changed it to turn.y and got no error message, but the enemy character has now disapeard so must be something else wrong.

 

EDIT: Is it ok to parent the controller to the pivot?

[Marleys Ghost]

which pivot? you seem to be pointing two things at the player? why not badguy.rotation.y?

 

PointEntity( TEntity entity1, TEntity entity2, int axis=3, flt rate=1, flt roll=0 )

 

PointEntity(badguy, player,3,1.0)

If stopanim2 = False
 If EntityDistance(jane,badguy) > 2.0 And EntityDistance(jane,badguy) < 16.0
	  bg_framebegin = 77
	  bg_frameend = 115
	  animate_badguy() ' badguy walk
	  UpdateController(bg_control,badguy.rotation.y,3.0,0, 0, 1,400,0)
 Endif
EndIf

 

 

 

 

I try and avoid parenting.

Ok thanks. I think I am slowly getting there. Been messing around for two weeks.

When it comes to pointentity I get confused between the character(badguy) its controller ( bg_control) and the pivot bg_pivot

[Marleys Ghost]

No need for the pivot bg_pivot, just steer your bg_control with the badguy mesh.

[cassius]

Thanks mg. Your code worked fine, exept the enemy character flickers wildly when close to main character. It did that a bit when I used moveentity but not as bad. Anyone know why?

[Marleys Ghost]

I have never had this problem myself, so its hard to speculate without demo/code/video.

[cassius]

it is probably how I coded it. I am going thru code now to improve it. Your help much apreciated.
