Hey everyone,
How would I do this? 
What do you want to achieve?
When a player clicks on a piece of clothing they will be prompt to purchase it. (Click to buy)
What is the issue?
I don’t know how to code this, I can’t find a video on YouTube that works and I can’t hire a scripter.
I’m not sure if I have researched enough, if there is a post or video about this that I have not seen please send it to me.
U could use a click detector to check if they press and then send a remote to server to calculate the purchase logic
How do I do that? I don’t know how to code.
You could go into the toolbox and choose from a variety of premade shirt purchasing machines. All you would need to do then is change out the decal and the shirt they are buying, which even then requires some knowledge of coding. If you want to do this easier, I suggest learning how to code from the Roblox Dev Hub or YouTube channels like Alvin Blox or The Dev King. They have some pretty good tutorials on Roblox coding.
I dont suggest using FMs as they usually contain bad practices to learn from but yes he should learn to code so he can come up w/ these solutions
