We are making a personal level editor with 3x3 matrices, all works successfuly at the moment, exceptly when the chained objects (in the parent matrix) are in negative scale... Im using Spine Pro for sprites.

I have to invert the matrix for negative scales?

Edit : sorry , my bad, i´m playing with negative angles, that is the problem.

HI!! i,m implementing this system in my game but i have troubles to interpret this function:

public Matrix3 setToRotation (Vector3 axis, float cos, float sin) {
   float[] val = this.val;
   float oc = 1.0f - cos;
   val[M00] = oc * axis.x * axis.x + cos;
   val[M10] = oc * axis.x * axis.y - axis.z * sin;
   val[M20] = oc * axis.z * axis.x + axis.y * sin;
   val[M01] = oc * axis.x * axis.y + axis.z * sin;
   val[M11] = oc * axis.y * axis.y + cos;
   val[M21] = oc * axis.y * axis.z - axis.x * sin;
   val[M02] = oc * axis.z * axis.x - axis.y * sin;
   val[M12] = oc * axis.y * axis.z + axis.x * sin;
   val[M22] = oc * axis.z * axis.z + cos;
   return this;
}

When i return this matrix, the val of (m00,m10,m01,m11) are too high .....maybe i´m wrong. This matrix is only for the prupose to take the m02 and m12 values and discard the rest??

Hi all!!

I post a ticket-bug in YoYo games telling a bug in relation of the switch animations states.....

http://bugs.yoyogames.com/view.php?id=18937

My question is, this is a general bug or its only in Gamemaker?

Can you be able to switch animations ingame with only 1 keyframe animation?

Sorry for my ignorance, but, how i do this?....

Its a sugestion, bind the very outside vértices of a bounding box with the mesh image..i think its not a lot of work in change..

Best regards

Yes, but im using gm:estudio and i think i don't have this function to do this

bind the bounding box vertices with the very outside vertices of the mesh image.... that is posible to do.....

Yes, but if i want to deform the mesh inGame, the bounding box does not take the new coordinares of the mesh image....

Is posible to implement this? in some sprites, instead of create a bounding box mesh, use the current mesh image like a bounding box.... Please? flaging if the mesh can colide or not?

I´m animator and somtimes when i want to animate a dog or a horse, with "other programs" i have the ability to put in depth a videoplay of an animal´s move and seeing this to begin making the animation ....(very educational)..

Sorry for my english!! Greetings!!

hi I managed normal mapping and specular with Game maker studio:

with the engine´s function i make this but i don´t know if the lighting is correct(sorry for my english):

normals follow rotation
