Apologies for the confusion in my previous explanation. Let's try to clarify the concept with a different approach. Imagine a carousel displaying 5 items at a time. To visualize this setup, picture a circle divided into 8 parts, with each segment numbered starting from the bottom as 0 and progressing clockwise. This layout corresponds to the faces visible in the carousel, which are numbered 0, 1, 2, 6, and 7.
animates = [0, 1, 2, 6, 7];
The movements of the faces can be represented as follows:
movements = [
{ pos: 0, right: [1], left: [7] },
{ pos: 1, right: [2], left: [0] },
{ pos: 2, right: [3, 4, 5, 6], left: [1] },
{ pos: 6, right: [7], left: [5, 4, 3, 2] },
{ pos: 7, right: [0], left: [6] },
];
When calculating the angle for movement, remember to divide by 8, not 9, for accurate positioning.
const animations = mov[direction].map(m => {
const angle = (m * 2 * Math.PI) / 8; //<--ensure the "8"
....
}
For a more realistic movement, consider dividing by 16 instead of 8. In this case, the visible faces would be 0, 2, 4, 12, and 14, located as follows:
animates=[0, 2, 4, 12, 14]
And their corresponding movements are:
movements = [
{ pos: 0, right: [1, 2], left: [15, 14] },
{ pos: 2, right: [3, 4], left: [1, 0] },
{ pos: 4, right: [5, 6, 7, 8, 9, 10, 11, 12], left: [3, 2] },
{ pos: 12, right: [13, 14], left: [11, 10, 9, 8, 7, 6, 5, 4, 3, 2] },
{ pos: 14, right: [15, 0], left: [13, 12] },
];
Adjust the angle calculation by dividing by 16:
const animations = mov[direction].map(m => {
const angle = (m * 2 * Math.PI) / 16; //<--ensure the "16"
....
}
Implement two-step movements within the carousel for enhanced functionality. Define the movements accordingly and update the animation function to support single or double-step movements.
movementsTwo=[
{ pos: 0, right: [1,2,3,4], left: [15,14,13,12] },
{ pos: 2, right: [3,4,5,6,7,8,9,10,11,12], left: [1,0,15,14] },
{ pos: 4, right: [5,6,7,8,9,10,11,12,13,14], left: [3,2,1,0] },
{ pos: 12, right: [13,14,15,0], left: [11,10,9,8,7,6,5,4,3,2] },
{ pos: 14, right: [15,0,1,2], left: [13,12,11,10,9,8,7,6,5,4] },
]
Update the animation function to accommodate one or two-step movements:
animateViews(direction: string, steps:number=1) {
this.animates.forEach((x: number, index: number) => {
//use the appropriate array based on the number of steps
const movements=steps==1?this.movements:this.movementsTwo;
const mov = movements.find(m => m.pos == x);
...
}
Introduce the functionality to move a specific element to the front within the carousel:
indexToFront(index: any) {
index = +index;
const pos = this.animates[+index];
if (pos) {
const mov = this.movements.find((x) => x.pos == pos);
const mov2 = this.movementsTwo.find((x) => x.pos == pos);
const anim = { direction: 'right', steps: 1 };
if (
mov.left[mov.left.length - 1] == 0 ||
mov2.left[mov2.left.length - 1] == 0
)
anim.direction = 'left';
if (
mov2.left[mov2.left.length - 1] == 0 ||
mov2.right[mov2.right.length - 1] == 0
)
anim.steps = 2;
this.animateViews(anim.direction, anim.steps);
}
}
Include a dropdown menu for easy selection:
<select #select (change)="indexToFront(select.value)">
<option *ngFor="let i of [0,1,2,3,4]">{{i}}</option>
</select>
Alternatively, add a click event to the carousel elements for intuitive navigation:
<div style="position:relative;margin-top:150px">
<div class="carousel" >
<div #element *ngFor="let i of [0,2,4,12,14];let index=index"
(click)="animates[index]!=0 && indexToFront(index)"
class="carousel__cell">{{index}}
</div>
</div>
For a more interactive experience, consider a pseudo-3D carousel designed to display 5 images simultaneously. Utilize CSS transform for smooth card movements and perspective effects.
Feel free to explore the updated functionality in a new stackblitz.
NOTE: While the current implementation may seem hardcoded, future enhancements may involve creating a more versatile component for dynamic usage.
