i siva,
tu use the buttons of your widget to move your player, you ll need to cast to your pawn blueprint
for this :

use the get player pawn node
drag the output of this node and connect it to a cast to “your character” node
drag the output of the node ad connect to the function you want to trigger

should look like this :

How do i make that for the movement?

for the movement it might be a little bit more tricky,
what i ll do :
1)create a boolean in your character BP, name it “ismovingforward”
2) create a custom event, you ll name moveforward , and add it a float input for scale
3) connect your custom event to the add forward input
4) on the event tick, add a branch, connect your bool as condition, on true output, connect a call to your custom event
should look like this :

in your widget set your boolean to true on the onclick event

in your widget , create an onrelease event of your button and set the boolean to false using same method as 5
do the same for every moves you plan to do, creating a bool and custom event for each.

an other way shoul be to bind events to inputs, be if you 're starting learning the engine, you can start with what i just gave you. and learn the “bind” system later.
hope it helps

adjust the get right vector to get more intended results.

you d rather use get owning player pawn thant get player pawn. (if you plan to do a multiplayer game)

no problem , i am the worst when it comes to “what i plug into object in casting” . i got a lot to learn.

anonymous_user_c6af9bd8 · July 17, 2016, 12:19pm

hi i see i can chose form 2 possibilities expose why when i do exactly what you do when i press left on the screen its moving on his own and dont stop.

anonymous_user_dcd9d04a · July 17, 2016, 12:23pm

because it won’t set to false (the bool)

anonymous_user_dcd9d04a · July 17, 2016, 12:24pm

use on release as well and set the bool to fasle the same way he explained.

anonymous_user_dcd9d04a · July 17, 2016, 12:25pm

anonymous_user_c6af9bd8 · July 17, 2016, 2:26pm

anonymous_user_dcd9d04a · July 17, 2016, 2:31pm

anonymous_user_c6af9bd8 · July 17, 2016, 2:54pm
