Okay, so I have a figure in XZ plain. I want to move it forward/backward and rotate at it's own Y axis, then move forward again in the rotation's direction, like the character in GTA 1.
Code so far:
Init:
spaceship_position = glm::vec3(0,0,0);
spaceship_rotation = glm::vec3(0,0,0);
spaceship_scale = glm::vec3(1, 1, 1);
Draw:
glm::mat4 transform = glm::scale<float>(spaceship_scale) *
glm::rotate<float>(spaceship_rotation.x, 1, 0, 0) *
glm::rotate<float>(spaceship_rotation.y, 0, 1, 0) *
glm::rotate<float>(spaceship_rotation.z, 0, 0, 1) *
glm::translate<float>(spaceship_position);
drawMesh(spaceship, texture, transform);
Update:
switch (key.keysym.sym) {
case SDLK_UP:
spaceship_position.z += 0.1;
break;
case SDLK_DOWN:
spaceship_position.z -= 0.1;
break;
case SDLK_LEFT:
spaceship_rotation.y += 1;
break;
case SDLK_RIGHT:
spaceship_rotation.y -= 1;
break;
}
So this only moves on the Z axis, but how can I move the object on both Z and X axis where the object is facing?
