gravity seems to be up instead of down

[Christuff]

Hello everyone,

 

First i've to precise that it's my first day with Unigine (so it's probably a basic problem).

 

I want to make a 3rd view of a character like it is done in the demo (player/actor00)

 

So i've taken code from this demo, the camera make the good thing like the demo.

But, here is my trouble, instead of going down, my character is going up.

Does anyone has a clue of where it can come from ?

 

In the picture attached :

blue arrow : getUp of the PlayerActor

red arrow : getViewDirection of the PlayerActor

physics gravity = -9.81

 

               // done on init, mNode is found before, and represent the object in the screen
	pa = new PlayerActor();
	pa.setPosition(mNode.getWorldPosition());
	pa.setMinThetaAngle(20.0f);
	pa.setMaxThetaAngle(60.0f);
	pa.setThetaAngle(20.0f);
	pa.setJumping(2.0f);
	pa.setPhysicalMass(120);

	persecutor = new PlayerPersecutor();
	persecutor.setControls(0);
	persecutor.setTarget(pa);
	persecutor.setAnchor(vec3(0.0f,0.0f,2.0f));
	persecutor.setMinDistance(2.0f);
	persecutor.setMaxDistance(4.0f);
	persecutor.setMinThetaAngle(20.0f);
	persecutor.setMaxThetaAngle(60.0f);
	persecutor.setPosition(vec3(-20.0f,0.0f,2.0f));
	engine.game.setPlayer(persecutor);

               // done on Update
               mNode.setWorldTransform(pa.getWorldTransform()  * rotateX(90.0f) * rotateY(90.0f)); // model need to be rotated.
	persecutor.setPhiAngle(pa.getPhiAngle());
	persecutor.setThetaAngle(pa.getThetaAngle());

 

Thanks for your help :(

Maybe cause your PlayerActor stays on mNode, and you move mNode?

Hi Christuff, it's always a good idea to post a functional minimal test case (.world/.cpp) for problem reproduction.

Bingo, my char have his collider enabled, god i'll probably never have thinked to that.

Noted, i've solved the problem, will think to do it next time.

 

Thanks to both of you for your replies :(
