See Dola work in Unreal Engine

The prompt: “In BP_Lamp, make the lamp blink: after BeginPlay, toggle LampLight’s visibility every 1 second. Compile and save it.” The model setting was Auto, and the editor was the stock Unreal Engine 5.7 with the Dola plugin.

Time-lapse of a real 2 minute 16 second Dola run: the director plans, the Blueprint agent edits BP_Lamp, and QA checks it in PIE before the change waits in review. Sped up about 13×.

We checked the result ourselves in the editor, not only Dola’s own QA: the timer calls ToggleLampLight every 1.0 s with Looping on, the function toggles LampLight, and the Blueprint compiles with no errors. One untidy detail stayed in: Dola wired a second Lamp Light getter into the existing Set Intensity node, which does nothing harmful.

Edits land in the Changes panel first. You can open the diff in Unreal, then keep the change or put the old asset back.

The prompt asked for a near-black full-screen background, a 72pt bold orange “LAMP DEMO” title with a soft shadow, and Play, Settings and Quit buttons in 380 × 76 size boxes, 18 px apart, with a dark fill that turns orange on hover and 30pt bold white labels.

Time-lapse of a real 3 minute 49 second Dola run: one prompt becomes WBP_GameMenu with a styled title and three buttons, compiled, saved and checked by QA. Sped up about 18×.

We checked it in the UMG Designer: the tree is RootCanvas, Background, TitleText and MenuList, with PlaySlot, SettingsSlot and QuitSlot each holding a button and its label. Selecting the list reads 380 × 264, which is three 76-tall buttons plus two 18 px gaps. It compiles. We did not test the hover colour by hand, so we only claim what you can see.

With the editor shut, Dola still answers from the project on disk and says where its answer comes from. The project here has one C++ module, ReviewLive, and its Blueprints folder holds BP_Lamp, BP_Crate, BP_Door and BP_Chest. Both match the files.
