E4-Q1 Multiple choice

A prototype requirement says: "A pressure plate opens a gate while the player stands on it, then closes the gate when the player leaves." Which implementation best supports reliable testing and later adjustment?

Use a plate trigger that calls Open() and Close() on a separate gate script. Put movement, player detection, sound, animation, UI updates, scoring, level transition logic and every other level rule into one large scene controller script. Animate the gate open in the editor timeline only and rely on the player to step off the plate at the correct time during the review. Duplicate the gate mesh into open and closed positions and manually enable the right version during the presentation whenever the player steps on the plate.

A teammate asks you to modify an existing player pickup script before a milestone build. Which practices should you apply? Select all that apply.

Select all that apply.

Identify the required logic before editing, including the trigger condition, score change, feedback and reset behaviour. Expose designer-tunable values such as score amount, rotation speed or audio clip reference instead of hard-coding everything. Use engine events and components, such as collision or trigger callbacks, where they match the behaviour being implemented. Use console output, breakpoints or the engine debugger to confirm the script runs under the intended conditions. Edit production files directly without checking version control because pickup scripts are usually small. Merge the pickup, player movement, UI, camera and audio systems into one script so there is only one file to open.

E4-Q4 Fill the gaps

Before reusing an imported 3-D asset in gameplay, check its , connect its , add an appropriate , and store the configured object as a or equivalent reusable engine object.

E4-Q5 True or false

After a configured object is converted into a prefab, Blueprint or equivalent reusable object, its instances no longer need validation after integration into scenes.

True False

E4-Q6 Multiple choice

A designer says a locked door mechanic "works" because the door mesh is in the level. Which description best represents a playable gameplay loop for that element?

Approach, prompt, input, lock check, then open or locked feedback. The door model is placed near the player start position and has a high-resolution material, but no input handling, state change, prompt, sound, animation or objective feedback is implemented. The level designer tells the reviewer verbally that the door would open in the final game if the full interaction system had already been completed. The door opens only when the developer manually changes a variable in the inspector during the presentation instead of responding to player input.

E4-Q7 Fill the gaps

A 3-D interaction system may use the to read keyboard, mouse, controller or VR controls; to detect triggers and impacts; the to play character or object motion; and to display prompts, health, score or objective feedback.

A prototype runs smoothly on a gaming desktop but stutters on the target classroom laptops. Which responses are appropriate before confirming the gameplay element? Select all that apply.

Select all that apply.

Profile frame rate, memory use, input responsiveness and key stutter points on the target laptops. Optimise expensive scripts, repeated per-frame work or unnecessary runtime allocations. Reduce asset cost where appropriate, such as texture size, shader complexity, object count or level-of-detail settings. Adjust lighting, camera effects or visual density if needed while preserving the intended mood and readability. Increase post-processing and particle effects so the presentation looks more impressive despite the stutter. Assume the packaged build will perform like the desktop editor and continue without further testing.

E4-Q9 Short answer

During QA for a locked door, you record: "Condition: player without key interacts with door. Expected result: door remains closed, locked sound plays, locked message appears." What is this kind of specific condition and expected result called?

E4-Q11 Multiple choice

A prototype sequence works in the engine editor. The assessor will review a packaged build. What is the best next testing decision?

Run the packaged build end to end. Skip build testing because editor play mode uses the same gameplay scripts, scene objects and designer-facing values, so the presentation build should behave identically on every machine. Only inspect the scene hierarchy because runtime behaviour has already been proven in the editor and the build process cannot change input, shader, path or scene-list behaviour. Record the editor window with debug tools visible so any build issue can be explained during review instead of validating the actual presentation form.

E4-Q12 Fill the gaps

For a stakeholder review, define the intended of events, confirm the fit of mood and player goal, confirm the fit of milestone scope and known limitations, and confirm the fit of platform, settings and performance.

E4-Q13 Select all that apply

A live prototype review is scheduled for tomorrow. Which actions support final readiness and risk control? Select all that apply.

Select all that apply.

Clear known compile errors and investigate runtime errors shown in logs. Run the intended sequence from start to finish in the presentation form. Triage defects by impact on the required sequence and document known limitations. Freeze the build when it is ready and archive evidence of testing. Add several new mechanics after the final test so the prototype appears broader. Use only the developer's best editor run and avoid documenting issues that remain.

E4-Q14 True or false

A prototype sequence can run without technical errors and still fail the brief if the player goal is unclear, feedback is confusing, or the mood and pacing do not match the intended experience.

True False

E4-Q15 Numerical

You are checking a prototype combat sequence for a target of 60 frames per second on the review hardware. To estimate whether code and rendering work fit the target, calculate the approximate maximum time budget per frame in milliseconds. Enter the value to two decimal places.

E4-Q16 Multiple choice

A packaged prototype runs on the developer machine, but on the review machine some textures are missing and controller input does not respond. Which response best aligns with technical readiness for presentation?

Check build settings, asset inclusion and input configuration, then rebuild and retest. Tell the reviewer to imagine the missing textures and use keyboard input instead because the main logic is present and the prototype worked on the developer machine. Delete the missing materials and controller support so the build no longer reports those problems, even if the prototype no longer meets the agreed presentation requirements. Run the editor version on the developer machine only and mark the packaged build as ready because a successful editor test is enough for stakeholder review.

E4-F1 True or false

A static 3-D model becomes an interactive game object only when it is combined with the necessary engine configuration, such as components, scripts, collisions, materials and references.

True False

E4-F2 Multiple choice

Before coding a new pickup mechanic, what is the best first step?

Break the requirement into clear behaviour logic, expected feedback and testable outcomes. Import as many pickup meshes as possible before defining interaction rules. Add the mechanic directly to the final build without testing in the engine. Use the highest-resolution texture available so the pickup is easy to see.
