Click on Entity

[MacTony]

Hello everyone! I have a question. How to make sure that when you click on an object (Entity), the object can do something? In Unity, this is done using the “OnMouseDown” event. Thank you in advance!

Raycasting Entity Selection

Raycasting only works if the entities have colliders. In your particular instance, I would approach the problem like this: Get the starting mouse coordinate (when the user presses down) Get the ending coordinates Turn the 2D mouse coordinates into 3D world coordinates (Might help: http://doc.xenko.com/latest/en/manual/physics/raycasting.html ) Loop over all the entities and check if they are inside the rectangle (This is going to involve a bit of maths)
