Give the model to the static mesh in UE4/5C++ [simple analysis]

Table of contents

Steps

code:

---

We all know that the model can be imported into the static mesh in the blueprint, just drag it in.

But in c++, how should we find the model we want from the content and put this model into the static mesh?

First we created a simple actor header and cpp file.

won't create look at this:

(1 message) The basic operation of ue4/5 blueprint and c++ mixed basic introduction (suitable for novices with blueprint foundation and c++ foundation, create your own blueprint)

Steps

As shown in the picture:

​

Then we need to create a static mesh component and place it under the root component, remember to add the header file at the header file:

​

​

Then we can find the required files under the resource folder content:

​ 

You can see that the following paragraph is the address of the model:

​

It is worth noting that our address cannot be filled in wrongly. Generally, if it is wrongly filled in, it will cause the compiler to crash, which is a very serious problem.

Another point worth noting is that the path starts with /Game instead of your project file. No matter what the name of your project file is, it must start with /Game, otherwise an error will be reported.

Then the addition is complete:

We don't need to set up the most primitive static mesh in the blueprint:
