The first step in UE4 Blueprint programming

recognize the color and variable types in the UE4 Blueprint :

Each color in the UE4 corresponds to a different variable, and the color of the connection point and line represents what type of variable is here. For beginners, the first to see so many connection points,

May be very confused, how to even, if you know the color corresponding to the variable type and then to find the corresponding module to connect, the efficiency is much higher.

This is also the first step in starting blueprint programming.

white line in Blueprint :

logical white line : Logical sequence line, if there is no branch, you can only one by one in series, the middle can not be broken. (currently only found on modules connected with logical white line can interrupt point debugging)

The beginning of the white line is usually an event derivation (such as animnotify_ispunching1 and Animnotify_ispunching2 in the animation montage (montage) are defined in the events).

White line branches such as branch (if), Doonce (only once), do N (execute n times).

attitude White line : This picture is Animation Blueprint Type Blueprint white line, and above said White line is different, here the white line at both ends is to represent the character posture (Pose), here the white line can only one-to-one connection, cannot one to many, if need a pair more, You can save Pose first, then use cached Pose to get it.

status white line : After you create a new animation state machine in the Animgraph in Animation Blueprint Type Blueprint, double-click the state machine to enter the state machine internal edit state

Common Modules :

Branch Module (IF)

Select module (switch)

Foreachloop, Foreachloopwithbreak module (foreach)

Get/set Series Modules

IsValid Module (checks if this blueprint is valid and valid to the right (the blueprint is executed from left to right))

Cast series modules (type conversion module, as keyword in C #)

Printstring module (displays input values in the Run window and log window)

The type conversion module is automatically generated when connected
