Hello @dsdsdsds,
A good place to start:
Break down what is required first:
- Array of images < Assuming you have already done this.
- Access a random element of the array.
This reference may help:
random() / Reference / Processing.org
You will have to convert the float to an int to access elements of array:
int() / Reference / Processing.org - Search for timer (or related keywords) in this forum for examples of timers.
- Write some code to understand each element above.
- Start piecing the elements of code together and later integrate it into your project.
:)
